hot rolled nm450 mechanical properties inventory 2021

Experiments have proved that the outstanding feature of the precipitation-strengthened NM450 mechanical properties, wear-resistant plate in terms of mechanical properties is that the yield strength is greatly improved. For example, the yield strength of the wear-resistant plate after precipitation strengthening treatment reaches 480-8l0MPa, and the yield strength ratio is 0.55-0.56; the wear-resistant plate that uses molybdenum, vanadium, and iron composite alloying, the yield ratio after dispersion strengthening is 0.60- 0.65.

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 NM450 mechanical properties 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.

According to the separate performance report released by India's Jindal stainless steel (Sisal) Co., Ltd. (JSHL), as of March 31, 2020, due to the global economic slowdown, epidemic situation, imports and other factors, its NM450 mechanical properties stainless steel sales decreased by about 10% to 600000 tons from 667000 tons in the previous fiscal year, and its net sales decreased by nearly 7% to 83.396.9 billion rupees, with the same gross operating profit (EBITDA) After tax profit increased by 22.4% to 3.203 billion rupees. The adoption of the new tax system has a positive impact of RS 220 million on after tax profits.
