1.4362 duplex chrome steel

We produce ASTM/ASME Grade 304, Grade 304L,304h, 316, 316L, 316H, 316TI, 321, 321H, 309S, 309H, 310S, 310H, 410S, 2205, 904L, 2507, 254, gh3030, 625, 253MA, S30815, 317L, Type 317, 316lN, 8020, 800, 800H, C276, S32304 and others special requirement stainless steel grade.

Heat-resistant steel H20N12S2 is a chromium-nickel-silicon austenitic stainless steel, grade immune to oxidation in air to a temperature of 950 °C. H20N12S2 has a chemical composition just like H25N20S2, X15CrNiSi25-21, 1.4841. Most of the austenitic stainless steels may be readily welded utilizing fusion or resistance methods. Siddhagiri Metals and Tubes is a recognized suppliers of Stainless Steel 309.

Because of its excessive chromium and low nickel content, SS 309 can be utilized in sulfur containing atmospheres as much as 1832°F (a thousand°C). The metal is not really helpful for use in highly carburizing atmospheres since it displays only average resistance to carbon absorption. UNS S30900 Steel may be utilized in slightly oxidizing, nitriding, cementing and thermal biking applications, albeit, the maximum service temperature must be reduced.

For product thicknesses over 12mm the double-V butt weld must be most popular as an alternative of a single-V butt weld. The included angle should be °, when using MIG-welding about 50° is sufficient. tack welds should be affixed with comparatively shorter distances from one another (considerably shorter than these of non-alloyed steels), to be able to prevent robust deformation, shrinking or flaking tack welds.

• Stainless Steel 309 (UNS S30900) is an austenitic chrome steel developed to be used in excessive temperature corrosion resistance functions.
• Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C).
• The alloy resists oxidation as much as 1900°F (1038°C) beneath non-cyclic conditions.

Our stainless production range

309 Stainless Steel may be simply welded and processed by normal store fabrication practices. Siddhagiri Metals and Tubes is a well-known Supplier, Exporter, Manufacturer and Stockist of Stainless Steel 309. We supply EN 1.4828 Steel in varieties such as Seamless Pipe ASTM A312, Seamless Tube ASTM A269, Welded Pipe ASTM 312, Welded Tube ASTM A269, Flanges ASTM A182, Fasteners, Pipe Fittings ASTM A403, Tube Fittings, Forged Fittings ASTM A182. We are an ISO Certified suppliers with 25 years of experience on this area.

1.4828 is also appropriate for laser beam fusion slicing with nitrogen or flame chopping with oxygen. The cut edges only have small heat affected zones and are typically fre of micro cracks and thus are nicely formable. While selecting an applicable course of the fusion minimize edges may be converted immediately. Especially, they can be welded without any additional preparation. While processing solely stainless instruments like steel brushes, pneumatic picks and so forth are allowed, so as to not endanger the passivation.

When heated between 1202 – 1742°F (650 – 950°C) the alloy is topic to sigma part precipitation. A answer annealing therapy at 2012 – 2102°F (1100 – 1150°C) will restore a level of toughness.

Chemical Composition ¹

It accommodates less nickel in its composition than Type 310 and a lower carbon amount than its Type 309 counterpart. The reduced nickel permits for higher resistance against hydrogen sulfide, particularly at high temperatures. Additionally, the lower quantity of carbon in its composition gives Stainless Steel 309S utilization in areas where excessive temperature gases could pose an issue.

We have thousands tons stock of stainless steel sheet and coil with various size and grade,mainly include austenitic stainless steel, martens stainless steel (including precipitation hardened stainless steel sheet & coil), ferritic stainless steel, and duplex stainless steel.
