Tel:0086-769-23190193 AISI SAE 4140 Steel - JIS SCM440 - DIN 1.7225 - Songshun 4140 steel is medium hardenability steel with good strength and good comprehensive mechanical properties after heat treatment. It has good manufacturability. The maximum temperature of use is 427 °C. It can be used to make turbine fastener, tool bodies, forming dies, brake dies and etc.

ASTM 4140 Steel 1.7225 42CrMo4 SCM440 - OTAI Special

ASTM 4140 Steel is a Alloy Structural Steel belong to ASTM A29/A29M Steel Grade standard. AISI 4140 used in Oil and Gas industry and Large Machinery Strutural. 4140 Steel China Supplier and factory Otai Special Steel Supply ASTM 4140 steel in Round bar, Plate, Alloy > 4140 Peerless SteelAlloy > 4140 This medium carbon alloy steel grade is widely used for many applications requiring high tensile strength and ductility combined with hardness in the R/C 40 range. The cold finished 4140 alloy steel bars are calcium treated; this addition greatly increases cutting speeds and tool life without sacrificing mechanical properties. DIN 1.7225 / AISI 4140 alloy - ALTA Special SteelThe higher carbon content of AISI 4140 gives greater strength and heat treatment capabilities in comparison to AISI 4130, however it does have inferior weldability characteristics. Applications :Widely used for a variety of applications in the oil and gas sector.
