a516 grade 70 equivalent pipe for general structural purpose

We are a professional a516 grade 70 equivalent pipe steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product a516 grade 70 equivalent pipe quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

The abrasion resistant a516 grade 70 equivalent pipe steel plates, which also known as wear resistant steel plates, are among our main business scope. There are various abrasion resistant steel grades on the market. Among them, NM400, NM450, NM500, HARDOX400, HARDOX500, AR400, AR500, etc. are most popular. Meanwhile, NM400, HARDOX400 and AR400 are equivalent to each other. NM500, HARDOX500 and AR500 are also equivalent abrasion resistant steel materials.

The wear-resistant layer of a516 grade 70 equivalent pipe wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy a516 grade 70 equivalent pipe carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of a516 grade 70 equivalent pipe etc. steel material.
