Alloy Steel Plate SA 387/A 387 Oil Tank Boiler Steel Plate

ASTM A 387, ASME SA 387, is one of our most popular products. It is a low alloy pressure vessel quality steel for high temperatures. We have a wide range of plate sizes available and thicknesses range from 6 – 100mm. 

The ASME SA387 standards covers the supply of weldable chrome molybdenum alloy steel plates for pressure vessels used in elevated temperature service. 

The added molybdenum and chromium provides excellent corrosion resistance and high temperature resistance respectively.

ASTM A515 Gr. 70 Carbon Steel Sheets

The advantage of high strength in ASTM A515 Gr. 70 Carbon Steel Sheets immediately becomes a disadvantage when considering formability and machinability. While fabrication of ASTM A515 Carbon Steel Grade 70 Slatting Coils we adapt various heat treating methodologies like process annealing, full annealing, isothermal annealing, quenching, and normalizing to enhance their strength and toughness.

 

The resistance to pitting and crevice corrosion in ASME SA 515 Gr. 70 CS Perforated Coils increases with the content of chromium, molybdenum and nitrogen in the steel.

 

The Carbon Steel A515 Grade 70 Plates material must meet a minimum of 70 ksi tensile strength with 21% minimum elongation, when cold working, CS Grade 70 Plate material may be readily bent or cold formed as is typical of plain carbon steels.
