AISI SAE ASTM 4140 steel coil steel plate 1.7225 42crmo4 Steel Plate
Product Detail
4140 is a structural steel made in the United States. Executive standard: ASTM A829/A829M or AMS 6414 / AMS 6415. For 1.7225 steel plate En Standard is EN10083-3.
The tpye steel plate is a chromium molybdenum low alloy steel with much higher strength and toughness than typical steel grades. In addition, the carbon content of this alloy is reduced while limiting the thickness strength, providing better weld ability than its 4140 steel counterpart. These characteristics make AISI 4140 a popular choice in the aerospace industry for manufacturing commercial and military aircraft components that require high strength and low weight. Examples include gears, piston pins, etc. Other uses of 4140 steel include automotive parts, cutting tools, and drilling and mining machinery.

Machinable Type
4140 /1.7225 Alloy Cold Rolled Steel Sheets offer good weld ability without compromising steel abrasion and impact resistance. It is commonly used in structural applications, including gears, fasteners, and some aircraft exterior.
Annealed Steel is "softer" than normalized steel and offers higher work ability while normalized steel offers a higher strength tolerance.
4130 Steel has good mach-inability, good weld ability and can be heat treated. Our material is annealed and meets AMS 6350.
