双相钢253MA钢板 耐高温钢板
253 ma is a kind of heat resistant Austenitic stainless steel (Austenitic stainless steel), for high creep strength, creep strength and good resistance to corrosion of application and design. The temperature range is 850 ~ 1100 ℃. The chemical composition of 253 ma is balanced, make the steel at 850 ℃ to 1100 ℃ temperature range has the most appropriate comprehensive performance, as follows: high resistance to oxidation, the oxidation of skin temperature as high as 1150 ℃, high variant variable capacity creep and creep rupture strength, in most of the gas medium has good resistance to high temperature corrosion and brush scale corrosion resistant ability, higher yield strength and tensile strength of at high temperature, good formability and weldability, and enough to machinability.
253MA钢板 镍铬钢合金元素铬和镍之外，253MA不锈钢还含有少量的稀土金属（Rare Earth Metals,REM），从而明显地改善了其抗氧化能力。添加了氮以改善蠕变性能并使这种钢成为完全的奥氏体。尽管铬和镍含量相对来说较低，但这种不锈钢有许多情况下具有与高合金化的合金钢和镍基合金相同的高温特性。
253MA化学成分：
碳：(C) 0.05～0.10,
锰：(Mn) ≤0.80,
镍：(Ni) 10.00～12.00,
硅：(Si) 1.40～2.00,
磷：(P) ≤0.040,
硫：(S) ≤0.030,
铬：(Cr) 20.00～22.00
锘：(No) 0.14¬¬—0.20
铈：（Ce）0.03—0.08
253MA广泛应用于烧结设备、高炉设备、钢熔化、熔炉和连续浇铸设备、轧钢机（加热炉）、热处理炉和附件、矿物设备及水泥生产设备等。
