AISI 4140 steel bar is widely used as tool steel in industrial applications.And we are professional astm 4140 steel alloy supplier,stockist and exporter.AISI 4140,SAE 4140,EN19 Plate Sheet Stockist,Supplier 4140 alloy steel is a low alloy steel that contains chromium,molybdenum,and manganese.Because it contains chromium and molybdenum it is sometimes referred to as Chromoly steel.It has high fatigue strength,excellent strength to weight ratio,abrasion and impact resistant,good ductility,and has excellent torsional strength.
Such as the horizontal eccentric shaft of the horizontal forging machine,the crankshaft of the forging press,and etc.And the equivalent grade for it is DIN 1.7225 and JIS SCM440.4140 Steel properties and heat treat as below.AISI 4140 Steel Characteristics.It is low alloy steel with chromium,molybdenum,and manganese.China Ss400 Ss41 S45c Steel Plate / Ss400 Ss41 S45c Steel China Ss400 Ss41 S45c Steel Plate / Ss400 Ss41 S45c Steel Sheet,Find details about China Alloy Plate,Alloy Steel Sheet from Ss400 Ss41 S45c Steel Plate / Ss400 Ss41 S45c Steel Sheet Mat.No.1.2726,DIN 26NiCrMoV5

carbon,low-alloy steels have been classied by composition using a system devised by SAE and eventually AISI.In this chapter,the steels thus classied have AISI/SAE before the steel code number,for example,AISI/SAE 1040 steel.The system is based solely on composition.In the four- or ve-digit code designation,
