No. 60 Gang Material Name: High quality carbon structural steel Grade: 60 Standard: GB / T 699-1999 Japan corresponding grades: S58C corresponding German brands: C60 (1.0601), CK60 (1.1221), Cm60 (1.1223) corresponds to US grades: Features and application range of 1060: No. 60 steel for sub-eutectoid steel, strength, hardness and elasticity are very high, when the cold plastic deformation is low, less cutting, welding and poor hardenability, water quenching cracks tend to have large use more normalizing parts. No. 60 for the manufacture of steel shafts, spring ring, axle, various gaskets, cam, rope and other larger force, working under friction conditions, requiring high strength, abrasion resistance and a certain elastic parts. 2 die bonding repair areas where it is the only among the hardness of the steel rod is better for air-cooled steel, cast: If ICD5,7CrSiMnMoV ... etc. Drawing automobile sheet metal cover mold and large metal sheet metal stamping dies, the tensile parts repair can also be used to make stiff dough. Also in use is also something that needs to be aware of: 1. wet site before construction, welding before drying to 150-200 ° C 30-50 minutes. 2. usually impose above 200 ° C preheated air cooling after welding, then the best possible implementation of stress relief. 3. Multi-layer surfacing place to CMC-E30N base, get better welding results.
