what is Q355GNH steel steel shapes and sizes chart

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials what is Q355GNH steel. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

There are many kinds of wear-resistant steel, which can be divided into high manganese steel, medium and low alloy wear-resistant steel, chromium molybdenum silicon manganese steel, wear-resistant corrosion steel and special wear-resistant steel. what is Q355GNH steel, Wear resistant steel is widely used in mining machinery, coal mining and transportation, engineering machinery, agricultural machinery, building materials, electric machinery, railway transportation and other departments. As the name shows, wear-resistant steel is very wear-resistant, it is very durable, service life is very long.

The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. what is Q355GNH steel, 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.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick what is Q355GNH steel steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.
