The cold working performance of GL-DH 40 oil platform engineering steel and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of GL-DH 40 oil platform engineering steel and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
VL E460 steel: is a structural steel plate for ships and offshore engineering."VL" stands for the abbreviation of "DNVGL", which is a standard certified by the two classification societies of DNV (Norway) and GL (Germany). The yield strength is 460. Different classification society certifications, different grade requirements and different yield strengths can be selected according to different needs.
GL-DH 40 oil platform engineering steel product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering
Global GL-DH 40 oil platform engineering steel crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global GL-DH 40 oil platform engineering steel crude steel production decreased to 443.03 million mt, down 1.4 percent year on year.
