BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's impact test S355ML industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate impact test S355ML market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

There are many types of impact test S355ML etc. alloy steel plates, which can be divided into different types according to different standards. If divided according to the element composition of the alloy, the alloy steel plates can be divided into four types. The first is chromium steel, in which chromium is an important part of alloying elements. The second type is chromium-nickel steel, the third is manganese steel, and the last type is silico-manganese steel. The types of these alloy steel plates are named according to the composition of the alloying elements contained in the steel, so you can roughly understand their composition based on their names.

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

The steel such as impact test S355ML delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

42CrMo alloy steel impact test S355ML: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

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 impact test S355ML 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.

The results of adopting two-level impact test S355ML service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and impact test S355ML after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
