Product Details

SWRCH18A SWRCH22A SWRCH8A ASTM Steel Wire Steel Industrial oil tempered steel wire

Quick detail:

Name: cold heading steel

Model: SWRCH22A

Features: SWRCH22A steel has good plasticity and easy forming; excellent welding performance and aging sensitivity; good machinability, cold drawing and normalizing state is better than annealing state.

Carbon steel wire rod for cold heading

S: Steel; W: wire; R: rod; C: cold; H: heading

SWRCH22A Swch: (steel wire cold heading) JIS mark: carbon steel wire for cold pressing below 0.18-0.23 0.10 0.70-1.00 0.030 below 0.035 above 470 (D project) above 440 (DA project)

Carbon steel wire rod for cold forging

22: carbon content is 0.22%

A: Aluminum deoxidized steel

Composition: C: 0.18-0.23; Si: ≤ 0.10; Mn: 0.70-1.00; P: ≤ 0.030; s: ≤ 0.035; al: ≥ 0.02 [1]

Difference between swch22a and SWRCH22A

Swch22a is a carbon steel wire for cold heading and cold forging material specified in JIS g3539

SWRCH22A is a carbon steel wire rods for cold heading and cold forging specified in JIS g3507. When this kind of wire rod is rolled into wire rod, the surface defects (such as seam seam) harmful to subsequent forging of the small steel embryo need to be removed to avoid cracking during forging. This kind of wire rod has no cracking guarantee in Taiwan. In fact, when it is used as fastener,

There is no difference between the two steels. SWRCH is more widely used
