NM450 plate material quality and thickness range
The NM450 plate material, medium and heavy steel plate can be processed for secondary processing. If the medium and heavy steel plates are not used later, the factory can process it into other plates, which will not waste resources and save cost. The overall market situation of NM450 plate material, medium and heavy steel plate is unstable, and the price changes every day. If the overall price rises, you can first observe for a period of time to find out why it has risen, and you can wait until the best price to buy.
The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing NM450 plate material high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.
Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. NM450 plate material Heat treatment process refers to the ability to change the microstructure and properties of NM450 plate material after heat treatment, including hardenability, hardenability, temper brittleness, etc.
