SK4 and C100S steel material are high carbon steel which can be  supplied annealed, quenched & tempered states due to the good hardness and toughness. The steel materials are used for making band saw blade, spring, washer, tape measure etc.

C67S and CK67 steel materials are the high precision carbon spring steel, can be hardened and tempered, annealed and cold rolled. These materials are widely used in the manufacture of various spring products due to its excellent elasticity and toughness, such as automobile shock absorber springs, construction tool, trowel, scraper etc.

60SiCr7, SUP7 and 60Si2MnA as equivalent materials, they have characteristics with high hardenability, high toughness and plasticity, low decarburization, good tempering stability, good working performance and low cost.

51CrV4 spring steel has good mechanical properties with high hardenability. Adding vanadium (V) refines the grain of steel, it reduces overheat sensitivity and improves strength and toughness. 51CrV4 steel heat treatment has high fatigue strength and a high yield ratio.

X32 CrMoV4 cold rolled steel strips have strict requirements on dimensional accuracy during the manufacturing process, including width tolerance, thickness tolerance, parallelism, straightness deviation, flatness deviation and twisting.

D6A steel is an alloy steel containing chromium, molybdenum, cobalt, nickel and other elements. D6A steel has excellent high temperature strength, high toughness and high wear resistance, so it is widely used in band saws, aviation, aerospace, automobile, machinery and other fields.
