The company is a leading company that sells S355ML ASTM equivalent steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold S355ML ASTM equivalent steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

The typical hardness of NM500 steel plate is 500 HBW, so it can withstand severe wear. NM500 steel plate is very suitable for working in strong wear environment, such as high strength ore and corrosive materials. NM550 steel plate is a kind of wear-resistant steel plate with an average hardness of 550 HBW. S355ML ASTM equivalent Its toughness is the same as that of NM500 steel plate, and it is used in high wear occasions. When the NM500 steel plate is upgraded to NM550 steel plate, the Brinell hardness is increased by 50 units, and the wear resistance life is prolonged without losing the toughness of the S355ML ASTM equivalent steel plate.

With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate S355ML ASTM equivalent shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.

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 S355ML ASTM equivalent, 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.

Delivery status: 16MnDR steel plate is normalized or normalized and tempered. 6-60mm16MnDR-40℃ impact, 60-120mm16MnDR-30℃ impact.Ultrasonic testing of 16MnDR steel plates: The S355ML ASTM equivalent plates delivered in the normalized or normalized and tempered state with thickness greater than 20mm and the steel plates delivered in the quenched and tempered state with thickness greater than 16mm shall be ultrasonically tested one by one.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the S355ML ASTM equivalent hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
