1Cr6Si2Mo Alloy Steel Plates Sheets 1Cr6Si2Mo Flat Bars For Boiler
Alloy steel, 1Cr6Si2Mo, martensitic type heat resistant steel, has better oxidation resistance at 800°C.
When compared with 1Cr5Mo steel, containing more than 1.5% Si, so that the tendency of tempering
brittle steel increases, parts at high temperatures for a long time will have brittle fracture.
1Cr6Si2Mo Ultrahigh strength steel has excellent corrosion resistance in sulfur-containing oxidizing atmospheres
and in hot petroleum media.
After normalizing, tempering heat treatment after a high strength and creep strength.
The steel quenching phenomenon, hot processing, such as cooling too fast, cracks will occur, should slow cooling.
Weldability is poor, can be used welding, not gas welding, preheated to be preheated to 300°C ~ 400°C, 750°C
tempering after welding treatment.
