SA514 Gr B steel material carbon steel sheet machinability

ASTM A387 Grade 91 SA514 Gr B steel material is a high level steel grade for outstanding heat and anti corrosion and oxidation resistance characteristics, it SA514 Gr B steel material satisifies most applications in fierce working environment with higher requirements.

The company attaches great importance to systematic management, and has passed the SA514 Gr B steel material ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on SA514 Gr B steel material quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled SA514 Gr B steel material plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy SA514 Gr B steel material steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, SA514 Gr B steel material, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.
