nm500 steel equivalent grades seamless pipe diameter

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

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. NM500 steel equivalent grades Heat treatment process refers to the ability to change the microstructure and properties of NM500 steel equivalent grades after heat treatment, including hardenability, hardenability, temper brittleness, etc.

The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. NM500 steel equivalent grades, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
