At present, en standard P295GH steel abrasion resistant steel plate thickness is between 8-100mm, the hardness of up to 500HBW. Thin steel sheet and ultra-wide steel plate has been developed for special use.

In terms of service, our service is a "one-stop" way of working. We have our own en standard p295gh steel processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as en standard p295gh steel cutting, welding, drilling, galvanizing, etc., at the lowest cost.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of en standard p295gh steel structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of en standard p295gh steel, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel en standard p295gh steel plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
