X12Cr13、1.4006

1.4006stainless steel

1.4006is a martensitic stainless steel with good hardenability. It has high hardness, toughness, good corrosion resistance, heat strength and cold deformation performance, and good shock absorption. Tempering at high or low temperature is required, but tempering should be avoided between 370-560 ° C.

 

characteristic:

stainless steel has good corrosion resistance and machinability.

Scope of application:

General blades, mechanical parts, type 1 tableware (spoon, fork, knife, etc.).

●quenching heating temperature: 1000-1050 degrees, holding for 1 to 3 hours, air cooling, according to the tempering temperature, the hardness will be different.

580-650 degree tempering, water cooling, hardness HBS is 254-302

560-620 degree tempering, water cooling, hardness HBS is 285-341

550-580 degree tempering, water cooling, hardness HBS is 254-362

520-560 degree tempering, water cooling, hardness HBS is 341-388

Temper than 300 degrees, air cooling, hardness HBS greater than 388

 

Heat treatment specifications and metallographic structure:

Heat treatment specifications: 1) annealing, slow cooling at 800 ～ 900 ℃ or rapid cooling at about 750 ℃; 2) quenching, oil cooling at 950 ～ 1000 ℃; 3) tempering, rapid cooling at 700 ～ 750 ℃.
