Performance characteristics of bulletproof FB2 steel plate shop primer

Compared with 12CrMoV steel, bulletproof FB2 steel plate, 12Cr1MoVR pressure vessel steel has higher oxidation resistance and heat strength. The creep limit of this steel is very close to the endurance strength value, and it has high plasticity under the condition of long-term stretching; the steel has good manufacturability and weldability, but it needs to be preheated to 300 ° C before welding, and the stress needs to be removed after welding deal with.

The wear-resistant plate bulletproof FB2 steel plate shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and bulletproof FB2 steel plate hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

TMCP process is an indispensable technology for our production of low alloy high strength wide and bulletproof FB2 steel plate thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy bulletproof FB2 steel plate and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

We are experienced shipbuilding and marine grade steel materials supplier and exporter with more than 20 years experience. For any question about the bulletproof FB2 steel plate shipbuilding steel materials, such as shipbuilding steel price, ABS EH36 steel specification, Lloyds grade A steel properties, AH36 steel mechanical properties, AH32 steel price, DH32 steel dimensions, difference between EH36 and DH 36 etc., please feel free to consult us.

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the bulletproof FB2 steel plate principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
