GB711-2011 Chinese steel standard is used in the manufacture of steel plates with a 16Mo3 steel equivalent thickness of not more than 150mm for navigating ships, fishing boats and marine engineering structures in ocean, coastal and inland waterway areas. CCS/NV/GL550 steel is a structural steel for ships and marine engineering, divided into four quality grades A, D, E, F, namely AH550, DH550, EH550, FH550, H is high-strength building materials, and 550 is the lower yield strength.

According to the latest statistics of alacero, the consumption of finished steel 16mo3 steel equivalent products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of 16mo3 steel equivalent nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of 16mo3 steel equivalent steel, can be used as an alloying element of low alloy steel.

The main problem of safety education in iron and steel enterprises is not that the company does not pay attention to it and does not implement it, but that the subordinate units do not strictly follow the company's requirements. In order to avoid the problem of safety education becoming a mere formality, BBN steel company improved the safety education model from the following aspects: First, the content of safety education should not only pay attention to the accumulation of safety knowledge, but also pay attention to the mastery of safety operation skills.
