What are the precautions during the cutting of nm450 steel elongation
With high-quality NM450 steel elongation steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our NM450 steel elongation steel market and improved the control of steel plate production quality.
Medium and heavy plate is widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. The surface quality of medium and heavy plate mainly refers to its surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plate. The surface quality of NM450 steel elongation, medium and heavy plate not only affects the appearance of the products, but also reduces the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate.
We have 4 typical production lines NM450 steel elongation, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
The basic principle of NM450 steel elongation, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.
