high strength steel plate S690QL hot forming

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, high strength steel plate S690QL it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.

ASTM A514 steel plate is a high yield strength, quenched and tempered alloy steel plate suitable for welding.
A514 steel plate has high strength, and high strength steel plate S690QL it can maintain mechanical properties even at very low temperature. At the same time, A514 steel plate also has good fatigue resistance, high toughness and low brittleness transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance.

The impression of most customers who have cooperated with us on the company is being professional and responsible. That mainly owe to our united and considerate team members. For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.

The strengthening mechanisms in metals mainly include solid solution strengthening, dislocation strengthening, fine grain strengthening, and second phase (precipitation and dispersion) strengthening. Alloying elements have the most significant strengthening effect on steel in the quenched and tempered state, because it makes full use of all four strengthening mechanisms. Martensite is formed during quenching, and carbides are precipitated during tempering, resulting in a strong second phase strengthening and greatly improving toughness. Therefore, obtaining martensite and tempering it is the most economical and effective comprehensive strengthening method for high strength steel plate S690QL.
