Shipbuilding steel plates or offshore platform plates are used to make hulls, offshore oil production drilling, platform pipe joints and other structural parts; Our ship steel plates are nine classification societies certified( American ABS, French BV, British LR, German GL, Norwegian DNV, Italian RINA, Japanese NK, Chinese CCS, South Korea KR ). These plates can be Z15 / Z25 / Z35. Our company stocks a large number of shipbuilding plates, offshore platform plate steel in stock.
A709 grade 50 low alloy steel,Alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel. Welding and forming of this steel plate should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary. We can supply ASTM, JIS, DIN and GB various standards alloy steel grades.
The effect of alloy elements of Q345B alloy steel plate on tempering transformation: improving the tempering stability The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved,A709 grade 50 low alloy steel.
