ASTM Weathering Steel Plate

What are the precautions in the cutting of hot rolled a242 type 1 steel

Q355NHE grade is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and E represents quality grade (A, B, C, D, E) composition. Q355NHE is an atmospheric corrosion-resistant steel plate, also called weather-resistant steel plate. It has the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature, and fatigue resistance.

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, hot rolled A242 Type 1 steel and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and hot rolled A242 Type 1 steel pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy hot rolled A242 Type 1 steel steel screw (Carbon and Alloy Steel Threaded Rod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of hot rolled A242 Type 1 steel carbon alloy steel screws from China and India, according to the itc's affirmative ruling.
