32CrNi2MoTiA protective steel

32CrNi2MoTiA protective steel is a kind of high corrosion-resistant super austenitic stainless steel. 32CrNi2MoTiA steel has much greater corrosion resistance than 316 ordinary stainless steel. However, compared with 904L (NO8904) stainless steel at high concentration, the corrosion resistance of 254SMO is slightly weaker.

Main components: carbon ≤0.02, manganese ≤1.00, nickel 17.5～18.5, silicon ≤0.8 phosphorus ≤0.03, sulfur ≤0.01, chromium: 19.5～20.5, 0.5～1.0, molybdenum 6.0～6.5, nitrogen 0.18～0.22

32CrNi2MoTiA protective steel physical properties

Density: 8.24g/cm3, melting point: 1320-1390 ℃, magnetic: no
Heat treatment: Insulation between 1150-1200℃ for 1-2 hours, rapid air cooling or water cooling.
Mechanical properties: tensile strength: σb≥655Mpa, yield strength σb≥310Mpa: elongation: δ≥35%, hardness: 182-223 (HB)

Corrosion resistance and main use environment

32CrNi2MoTiA protective steel is a kind of high corrosion-resistant super austenitic stainless steel. It is developed for the environment of halides and acids. It is widely used in harsh working conditions such as high concentration chloride ion medium and sea water. In various industrial occasions of acidic medium, especially in the acid containing halide, the 254 stainless steel coil is far superior to other stainless steels, and in some cases can be comparable to Hastelloy and titanium. The low carbon content and high molybdenum content make 32CrNi2MoTiA stainless steel have better pitting corrosion resistance and crevice corrosion resistance and intergranular corrosion resistance. It is a kind of high cost performance stainless steel, widely used in chemical industry, desulfurization and environmental protection at home and abroad.
Done is better than perfect.

1Cr6Si2Mo heat-resistant steel

1Cr6Si2Mo steel is a martensitic heat-resistant steel with good oxidation resistance at 800℃. Compared with 1Cr5Mo steel, the Si content is 1.5% more, which makes the temper brittleness tendency of the 1Cr6Si2Mo steel increase, and the parts will produce brittle fracture when working at high temperature for a long time. The steel has good corrosion resistance in sulfur-containing oxidizing atmosphere and hot petroleum medium. Chemical Composition(%) C≤0.08 Si:1.5-2.0 Mn≤0.37 P≤0.014 S≤0.001 Cr:4.0-6.0 Mo:0.45-0.6 Ni≤0.04 Mechanical properties Yield strength: 401Mpa; Tensile strength: 547Mpa; Elongation: 31.5% After normalizing and tempering heat treatment, 1Cr6Si2Mo heat-resistant steel has higher endurance strength and creep strength. The steel has an air quenching phenomenon. After hot working, if it is cooled too quickly, cracks will occur and it should be cooled slowly. Weldability is poor, electric welding can be used, gas welding is not suitable, preheating to 300
