hot rolled BV FH32 marine sheet, ASTM A131 shipbuilding steel has different grade levels. The ordinary strength shipbuilding steel grades are grade A/B/D/E. Their min. yield strength is 235 Mpa, and tensile strength is 400-520 Mpa. The higher strength shipbuilding steel grades are grade AH32/DH32/EH32/FH32, AH36/DH36/EH36/FH36 AH40/DH40/EH40/FH40. The min. yield strength of AH32/DH32/EH32/FH32 steel is 315 Mpa, and tensile strength is 440-590 Mpa. The min. yield strength of AH36/DH36/EH36/FH36 steel is 355 Mpa, and tensile strength is 490-620 Mpa. The min. yield strength of AH40/DH40/EH40/FH40 steel is 390 Mpa, and tensile strength is 510-650 Mpa.
In March, the daily output of key iron and steel enterprises fell on a month on month basis, while the overall inventory of hot rolled BV FH32 marine sheet and so on steel materials was lower but still at a high level. In terms of production, in March, according to the key statistics, the cumulative average daily output of pig iron, crude steel and steel for iron and steel enterprises was 1.824 million tons, 1.695 million tons and 1.766 million tons respectively, down 2.1%, 3.1% and 1.7% on a month on month basis.
Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. hot rolled BV FH32 marine sheet Heat treatment process refers to the ability to change the microstructure and properties of hot rolled BV FH32 marine sheet after heat treatment, including hardenability, hardenability, temper brittleness, etc.
The hot rolled BV FH32 marine sheet, medium and heavy steel plate can be processed for secondary processing. If the medium and heavy steel plates are not used later, the factory can process it into other plates, which will not waste resources and save cost. The overall market situation of hot rolled BV FH32 marine sheet, medium and heavy steel plate is unstable, and the price changes every day. If the overall price rises, you can first observe for a period of time to find out why it has risen, and you can wait until the best price to buy.
