C75 hardened spring steel for making construction tool trowel putty knives scraper blade
Guangzhou Cgoodsteel Co.,Ltd, produces C75 hardened Spring steel used in the manufacture of construction tool trowel putty knives scraper blades,  springs,  automotive and industrial suspension applications. Spring steel including C75 CK75 SAE 1075 AISI 1074, are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant deflection or twisting.
 
C75 steel grade equivalent to CK75, C75S, AISI 1074, SAE 1075;
chemical composition: C% 0.72-0.80, Mn% 0.60-0.90, Si% 0.17-0.31, S% max 0.035, P% max 0.035
