What are the potential applications of q355gnh steel beam

Since it was established in 2000. Based on the domestic rich q355gnh steel beam product resources and the great steel demand of the international market, our q355gnh steel beam service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

Medium thick steel plate refers to the steel plate with a thickness of not less than 3 mm but less than 20 mm. It can be produced by reversible hot rolling medium and heavy plate mill, and its thin products can also be processed by cold rolling mill. q355gnh steel beam, Medium thick steel plates are mainly used in boilers, shipbuilding, railway cars, automobiles, containers, military industry, national defense, construction, bridges and containers.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel q355gnh steel beam is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, q355gnh steel beam.
