Weldability of X20CrMoWV12-1 Stainless Steel
Preheating: Mandatory. Preheating to a temperature of 1200°F – 1400°F (650°C – 760°C) is required to prevent cracking.
Welding: Use qualified procedures. The material should be carefully handled during cooling, typically slowly to room temperature.
Post-Weld Heat Treatment (PWHT): Mandatory to restore ductility and reduce hardness. Perform stress relief at roughly 1100°F – 1400°F (590°C – 760°C) for 4 hours.
1.4935 Stainless Steel Heat Treatment
1.4935 (X20CrMoWV12-1) is a martensitic, creep-resistant stainless steel designed for high-temperature applications up to 650°C, often used in turbine blades and fasteners. It is hardened by heating to 1040°C–1050°C, followed by oil or air quenching, and then tempered to achieve high mechanical strength, typically between 700 and 950 MPa.
What is the density of AISI 422 stainless steel?
The density of AlSI 422 stainless steel is approximately 7.80 gam2 (0.282 lb/n2). It is amartensitic stainless steel known for high strength and creep resistance at elevatedtemperatures, often used in steam turbines, gas turbines, and aerospaceapplication.
What is the difference between 1.4935 and 1.4835 stainless steel?
1.4935 (X20CrMoWV12-1) and 1.4835 (253 MA) are designed for high-temperature environments, but they differ fundamentally in structure and application. 1.4935 is a hardenable, martensitic steel used for high-strength turbine blades up to ~650°C, while 1.4835 is an austenitic heat-resistant steel designed for excellent oxidation resistance in furnace components up to 1150°C.
