chemical composition of nm400 Hot Rolled Plate 2021

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. chemical composition of NM400, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

HARDOX steel chemical composition of NM400 is a famous wear-resistant steel brand. It is designated as Hardox400, hardox450, hardox500, hardox600. It has good wear resistance in general and special applications.

According to the monitoring of the Iron and Steel Association, at the end of October, the China Steel Price Index (CSPI) was 107.34 points, an increase of 1.24 points or 1.17% from the end of last year; the price of CIOPI imported iron ore during the same period was US6.38/ton, an increase of US.86/ton from the previous month, an increase of 28.57%. The price increase of iron ore is significantly greater than that of steel, and the impact on the production costs of steel companies will gradually become apparent, greatly reducing corporate profitability.
