Stainless Steel 416
Grade 416 steel is a free-machining stainless steel with a machinability of 85%, highest of all stainless steels. With most of the free-machining stainless steels, the machinability can be improved by adding sulphur, which leads to the formation of manganese sulphide inclusions. Addition of sulphur also reduces the formability, weldability and corrosion resistance of 416 steels to below that of grade 410. Because of their high machinability and low cost, grade 416 steels are available in highly tempered, hardened or unhardened forms.

Stainless Steel 431
AISI 431 / S43100/ 1.4057 SS 431 STAINLESS STEEL BARS
440 Stainless Steel, Stainless Steel 440b Round Bar431 is a high chromium-low nickel high hardenability Martensitic stainless steel with high strength and good corrosion resistance, as generally supplied hardened and tempered in the tensile range 850 – 1000 Mpa (condition T) Brinell range 248 – 302. Characterised by very good corrosion resistance in general atmospheric corrosive environments, good resistance to mild marine and industrial atmospheres, resistant to many organic materials, nitric acid and petroleum products coupled with high tensile and high yield strength plus excellent toughness in the hardened and tempered condition.
431 due to its excellent hardenability is capable of being through hardened up to Rc44, depending upon carbon content and section size. Small sections can be air cooled and larger sections oil quenched for maximum through hardness. Pre hardened and tempered 431 will also respond readily to nitriding achieving a typical surface hardness of over Rc65. The nitriding process however reduces the corrosion resistance and is therefore not generally recommended except for critical applications where the benefit outweighs all other considerations. Used extensively for parts requiring a combination of high tensile strength, good toughness and good corrosion resistant properties.

Austenitic SS 303
AISI 303 (SUS 303) Grade Stainless Steel
Stainless steel type 1.4305 is popularly known as grade 303 stainless steel. Grade 303 is the most readily machineable of all the austenitic grades of stainless steel. The machineable nature of grade 303 is due to the presence of Sulphur in the steel composition. Whilst the Sulphur improves machining, it also causes a decrease in the corrosion resistance and a slight lowering of the toughness. Alloy 409 is available as round / flat / sheet /hexagonal plate/ square /coil / pipe & fittings. The corrosion resistance of type 303 is lower than that for 304. The toughness is still excellent as with other austenitic grades. Property data given in this document is typical for bar products covered by ASTM A582. ASTM, EN or other standards may cover products sold by Tecni-Cable Ltd. It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet.

Austenitic SS 317 317L
Stainless steel AISI 317L has as its main characteristic the great addition of molybdenum to its chemical composition, which guarantees an increased resistance to chemical attack when compared with chromium-nicke-molybdenuml austenitic steels of the type AISI 316L. This grade has approximately 1% more chromium, nickel and molybdenum when compared with austenitic steel AISI 316L. Grade AISI 317L offers even better creep deformation characteristics and mechanical resistance to high temperatures when compared with conventional stainless steels. The American denomination “low carbon”, or simply “L”, of grade AISI 317L ensures resistance to sensitization during welding or when thermal processes are applied due to the low carbon in its chemical composition. The combination of molybdenum and nitrogen in the chemical composition of this grade is particularly effective in incresing the resistance to pitting corrosion and crevice, especialy in acid medium with chlorides and sulfur compounds at high temperatures. In addition, nitrogen also contributes to increasing the mechanical strength of the alloy. The main applications of AISI 317L are dedicated to the chemical industry, petroleum and petrochemical industries, industries producing paper and pulp, and as condenseres in power stations using fossile and nuclear fuels. It is intended where it is required to have corrosion resistance to strong organic acids, such as the naphthenic acids found in the petroleum refining.

Duplex Stainless Steel 31803
Duplex stainless steel – F51 / S31803 / S32205/ 1.4462
UNS S31803 and UNS S32205 are commonly referred to as Duplex 2205® material, whose “Duplex” name is derived from the mixed micro structure which contains about equal portions of ferrite and austenite. Developed more than 70 years ago in Sweden precisely for the sulfite paper industry where the Duplex’s were used to combat corrosion problems caused by chloride-bearing cooling waters and other aggressive chemical products. Since then there have been advancements in the composition such as the deliberate addition of nitrogen as an alloying agent, which afterwards quickly made Duplex the “workhorse” of stainless steels.
-
Duplex Stainless Steel 329
One of the earliest duplex steel which is reflected in its higher permitted carbon content. Its resistance to pitting (PREN about 32) and to crevice corrosion is below that of super duplex steels, therefore use in seawater is limited. Exposure to moderate and high temperature and less rapid cooling may cause embrittlement. Accordingly, design stress values in ASME II do not extend above 260°C for S32900. Impact values are high at room temperature. However, the proportion and orientation of ferrite in welds and base material may significantly affect toughness at subzero temperatures.

Hastelloy B2
Alloy B-2 / UNS N10665 / W.Nr. 2.4617
Alloy B-2 is a solid solution strengthened, nickel-molybdenum alloy typically used in extreme reducing conditions. Alloy B-2 has significantly lower carbon, silicon and iron compared to the predecessor, alloy B (UNS N10001). Compared to alloy B, alloy B-2 is less susceptible to weld zone corrosion in the as-welded condition. Controlling other alloying elements such as iron and chromium resolved potential issues with forming and shaping. Stringent chemistry control in the production of alloy B-2 allows the alloy to be used in the welded condition, and it is less susceptible to stress corrosion cracking under many conditions. Care must be taken in selecting the right alloy for the desired application. Alloy B-2 should not be used at temperatures between 1000°F and 1600°F as the alloy forms secondary phases that could decrease the ductility of the material.

Hastelloy C-276
Alloy C-276 is a nickel-chromium-molybdenum alloy with universal corrosion resistance unmatched by any other alloy. C-276 is also known as Inconel® C-276 or Hastelloy® C-276 and is an improved wrought version of alloy C in that it usually doesn’t need to be solution heat-treated after welding and has vastly improved fabricability. This alloy is resistant to the formation of grain boundary precipitates, specifically in the weld-heat affected zone. This attribute makes Alloy C-276 suitable for use in the as-welded condition.
Alloy C-276 has excellent resistance to both localized corrosion and oxidizing or reducing media. Because of its versatility, alloy C-276 can be used where corrosive conditions are likely to occur or in multipurpose plants. Alloy C-276’s native corrosion resistant properties extend to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater and brine solutions. It is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encountered in most scrubbers. Alloy C-276 has excellent resistance to pitting, stress-corrosion cracking, and oxidizing atmospheres up to 1900 °F (1038 °C). It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide.
