weather resistant SA588 grade A steel standard and specificaiton

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and weather resistant SA588 grade A steel 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 products are exported weather resistant SA588 grade A steel to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

As a leading weather resistant SA588 grade A steel, S420NL hot rolled plates and sheets supplier, we can supply structural steel S420NL plates up to 250mm. It is often delivered in normalized or normalized rolled condition. When customers need doing the third party inspection for S420NL steel plates,our mill would issue the MTC under format EN10204 3.2, the third party can stamped and report the result on our original MTC when inspection is done completely.

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and weather resistant SA588 grade A steel steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the weather resistant SA588 grade A steel steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. weather resistant SA588 grade A steel, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
