At the same time of doing well in A573 Gr 70 plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A573 Gr 70 plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
In 1045 steel plate, the ‘10’ means a basic carbon steel and ‘45’ designates the approximate carbon content. 1045 steel is included in the ASTM 830 (A830) family of specifications. A830 Grade 1045 hot rolled steel plate can be cut to various shapes, hammer forged and heat treated. 1A573 Gr 70 plate product is mostly used where greater strength is required than lower carbon steels. Welcome to contact us for hot rolled plates stock price.
12Cr1MoVR steel plate is suitable for medium and high temperature pressure vessels, and implements GB713-2014 standard. 12Cr1MoVR pressure vessel plate is usually delivered in normalizing + tempering state. According to the special agreement at the time of order, 12Cr1MoVR steel plate can also be delivered in annealing or tempering state, which significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A573 Gr 70 plate nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A573 Gr 70 plate steel, can be used as an alloying element of low alloy steel.
