Description

Free Cutting Steel Hex Bar with grade 12L14 / SUM23

1.Introduction of AISI 12L14
AISI 12L14 is a Standard Resulfurized and Rephosphorized grade Carbon Steel. It is a free machining steel and is commonly called AISI 12L14 Lead Steel.. Lead has been added to the chemical composition to provide an improved level of machinability. Although machinability is excellent, the added lead content reduces the overall strength of tht steel.

2.Equivalent grade to 12L14
SAE 12L14
Material No.: 1.9718
Standard:ASTM A29 / A29M
International steel grades: JIS: ~ SUM 22 L, ~ SUM 23 L

3.Application of 12L14 free cutting steel
Typical applications include high-speed screw machine products, spindles, bushings, hose fittings and many other items where excellent machining characteristics can be fully utilized.
