SA387/ASTM A387 GR 91 CLASS 2 AIloy Bar
Carbon alloy steel plate is a material worth considering when high temperature resistance and good corrosion resistance properties are required. It is a pressure vessel grade steel often used by manufacturers in the oil and gas industry.
Description
Thickness: 8 - 40 mm
Width: up to 3 m
Length: max. 12 m
Pipe: A213 Gr.T91; A335 Gr.P91
Applications: Used in the oil and gas industry, the nuclear industry and fossil fuel power stations, e.g. where fuel dispensers, heat exchangers or pressure vessels will be exposed to high temperatures.
Products Description
The use of deoxidized steel to produce ASTM A387 Grade 91 plate also affects its toughness. Since there are no free air molecules in the alloy, the opportunity for bubble formation is greatly reduced. As a result, there are no air bubbles, ASTM A387 Grade 91 Alloy Steel Plate is not porous, and there are no weak points in the material, resulting in a stronger, better product. To simplify identification, sedum alloy steel SA 387 Gr 91 plate is marked with a capital letter "K". Grade 91, heat treated in accordance with this specification. Any form of heat treatment of alloys, including ASTM A387 Grade 91 CL1 plate, results in high-quality materials capable of withstanding high temperatures. SA 387 Gr 91 cl2 bar also has high mechanical strength.
