What problems should be noticed in q345r jis cutting operation

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 q345r jis industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate q345r jis market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel q345r jis.

NM400 wear plate is widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery and other product parts. Such as excavator, loader, bulldozer bucket plate, blade, side blade, crusher liner, etc.. NM400 wear plate is also commonly used as high-strength structural steel with yield strength ≥ 800MPa. The main function of NM400 wear plate is to provide protection in places or parts where wear resistance is required, so as to prolong the service life of the equipment.

Its weatherability is the protection of the oxide layer of weatherproof steel. The mechanism of corrosion resistance of weathering steel is mainly based on the analysis of long-term exposed rust layer. Generally speaking, it is believed that weathering steel can form a dense layer of weathering rust through long-term exposure, which has a good protective effect on weathering steel, q345r jis.
