High-Temp Steel

SCMV1

JIS steel grade SCMV1

Chemical Composition (%)

C0.15
CR0.85
MO0.15
P0.03
S0.03

Applications

Japanese Industrial Standard steel grade per JIS specification.

Available Forms

Bar, plate, sheet, tube, forgings, strip, wire

Uses

Heat- and creep-resistant steel for elevated-temperature service with stable strength and oxidation resistance. Used in furnace parts, exhaust manifolds, turbine components, boiler tubes and engine valves.

Heat Treatment

Normally used in the solution-annealed or precipitation-hardened condition; stabilise/age per the grade (e.g., 650–800 °C ageing). Avoid long exposure in the sigma/475 °C embrittlement ranges.

Precautions

Maintain the recommended heat-treatment envelope; prolonged time in embrittlement ranges reduces ductility. Use descaling/protective atmosphere to limit scaling.
