Tensile strength, ksi [MPA]:85 to 110 [585 to 760]
Yield strength, min, ksi [MPa]/(0.2% offset):60 [415]
Elongation in 2 in. [50mm], min, %:18

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.

Generally speaking, the higher the strength of NV F32 hull steel heavy plate, weathering steel, the greater the hardness, while the plasticity and toughness will decrease. When the carbon content of weathering steel exceeds 1.2%, the hardness will increase, but the strength will not increase, but will decrease. Resilience will also decline quickly. When the carbon content is high, the cementite increases and forms network distribution, which weakens the connection between grains and makes the mechanical properties of steel worse.

The hardness of NV F32 hull steel heavy plate, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.

We have a professional production team and high-quality production equipment, and we also have a great NV F32 hull steel heavy plate advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the NV F32 hull steel heavy plate production of high-quality steel plates, steel pipes and other products that meet customer requirements.

We are willing to cooperate sincerely with you with high-quality NV F32 hull steel heavy plate products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services!
