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.
The high mechanical strength of Sandvik 253 MA permits for thinner tube wall constructions compared with utilizing materials of the ASTM 310 type. Despite the material’s high power, ductility just isn’t reduced, and good formability is maintained. Although not designed for aqueous corrosion resistance the high chromium and nitrogen contents give the grade a pitting resistance approximating that of 316. 253MA does nonetheless have a high carbon content so is highly prone to sensitisation from welding or service exposure.
Steel tends to spring, so it will be necessary to apply compensation. After chilly bending you don’t have to, however it is recommended in the case of bending, among others, pipes, to subject the product that will work at temperatures above 800oC to annealing. The plasticity of X9CrNiSiNCe is much better than plasticity of ferritic steels.
The Sandvik program of muffle tubes includes supplies suitable for every type of protecting gases and environments, covering service situations as much as 1200ºC (2190ºF). In common with all austenitic stainless steels, Sandvik 253MA has low thermal conductivity and high thermal expansion. Welding plans ought to due to this fact be rigorously chosen prematurely, in order that distortions of the welded joint are minimized. If residual stresses are a priority, resolution annealing could be performed after welding. The creep and creep rupture power values correspond to values evaluated by the Swedish Institute for Metals Research for inclusion in the Swedish Standard.
- Apart from the alloying elements chromium and nickel, 253MA stainless-steel also accommodates a couple of rare earth metals, which significantly enhance its antioxidant capacity.
- Despite its relatively low chromium and nickel contents, 253MA shares the identical high temperature properties because the high alloyed alloy steel and nickel-based alloy in lots of purposes.
- Nitrogen is added to enhance creep properties and make this steel a whole austenite.
Our stainless production range
Thermocouple protection tubes (pyrometer safety tubes) in a wide range of high-temperature corrosion resistant supplies. The Sandvik program includes materials appropriate for all sorts of protecting gases and environments overlaying operating temperatures up to 1200ºC (2190ºF). Muffle tubes in a variety of high-temperature corrosion resistant supplies.
The analysis is based on information submitted by AB Sandvik Materials Technology and Outokumpu Stainless and checks made by the Swedish Institute for Metals Research. Sandvik 253 MA just isn’t generally used in situations requiring great resistance to moist corrosion. The metal is, however, barely more resistant than ASTM TP304 to emphasize corrosion cracking in chloride bearing aqueous options. Its resistance is kind of the identical as that of ASTM TP316.
A ®, 1.4835, X9crnisince21-11-2 – Heat-resistant Steel
The mixture of nitrogen, carbon and niobium provides it a creep power twice as excessive as that of grade 310 and 309 at temperature of 871 °C. Stainless 253 MA is a lean austenitic heat resistant alloy with high strength and excellent oxidation resistance. 253 MA maintains its heat resistant properties by advanced management of micro alloy additions. The use of rare earth metals in combination with silicon gives superior oxidation resistance as much as 2000°F.
Welding of X9CrNiSiNCe metal is performed by arc welding by coated electrodes at oC, pure argon, plasma, and MIG (Ar + 0.03% NO, or Ar + 30% He + approx. 2.25% Co2). TIG and MIG present one of the best creep resistance at excessive temperatures.
