Description

Cold Rolled Hot Rolled Alloy Steel Plate SA 387/A 387 Boiler Steel Plate / Sheet

Product Description

A high quality chrome molybdenum alloy steel plate intended specifically for use in weldable carbon steel pressure vessels at elevated temperatures. Added molybdenum gives the material greater temperature tensile strength and the chromium provides improved corrosion resistance.

Characteristics

4140 Alloy Steel/SAE 4140 Steel Price is engineering steel supplied in quenched and tempered conditions. Very good machinability. High toughness. High creep strength. Repeated impact resistant capability.

Applications

4140 Alloy Steel/SAE 4140 Steel Price is use to producecomponents with high requirements on toughness, e.g. gear wheels, pinions, connecting rods, parts for mechanical engineering .
