Flame cutting of A387 grade 12 class 1 pressure vessel steel sheet

A387 grade 12 class 1 pressure vessel steel sheet product plate specification range: Thickness 3-150mm Width 1500-4020mm Length 4000mm-17000mm Heat treatment: annealing, or normalizing and tempering

In comparison between steel plates, hot rolled A387 grade 12 class 1 pressure vessel steel sheet steel plates are generally slightly harder than cold rail steel plates and have lower elongation. In cold-rolled steel sheets, the higher the grade, the softer the steel, the lower the yield point, and the higher the total elongation.

The Brazil steel is facing a "crisis of demand" as the epidemic of new crown pneumonia spreads in Brazil. The demand for A387 grade 12 class 1 pressure vessel steel sheet and so on steel will be reduced by 50% in April. The demand for the second quarter will be 40% lower than that in the first quarter. The demand for this year will be reduced by 20% compared with the same period this year. In 2019, Brazil's apparent steel consumption was 20.6 million tons, a year-on-year decrease of 2.7%; crude steel production dropped to 32.33 million tons, the lowest since 2016 (30.2 million tons).

The work performance of A387 grade 12 class 1 pressure vessel steel sheet etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
