What is the a516 grade 70 weight refining

Based on the main a516 grade 70 weight business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel a516 grade 70 weight products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Automobile steel sheet is mainly used to manufacture automobile girders (longitudinal and cross girders), frame and other structural parts. The automobile girder should not only bear heavy static load, but also bear certain impact, vibration, etc., so the steel sheet a516 grade 70 weight is required to have certain strength and fatigue resistance, as well as better stamping performance and cold bending performance to meet the requirements of cold stamping processing.

Pressure vessel plates a516 grade 70 weight are used to manufacture pressure vessel equipment in petrochemical, gas separation and gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The general heat treatment of Q345R plate is hot rolling, controlled rolling, normalizing. The impact temperature is normal temperature, 0 ° C, -20.

The mechanical properties of a516 grade 70 weight, boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.

a516 grade 70 weight, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.

We are the professional Chinese steel plate, steel pipe supplier. If you need any steel plate, steel pipe, we can put the steel plate, steel pipe order to our steel mill directly or collect these goods from our stock directly if we have enough ex-stock. Besides. if you need any a516 grade 70 weight offer or if you want to know the price and any other information about steel plate, steel pipe price, please be free to contact us.
