The SA514 Gr Q steel material material useful

SA387 Gr 11 Cl 1 steel has high brittle resistance, and also has good impact toughness in low temperature environments. It is suitable for refining and gas treatment in hydrogenation reaction and conversion equipment at high temperature. The maximum thickness of SA514 Gr Q steel material products can reach 250mm. According to different thickness and impact requirements, the heat treatment of A387 Gr 11 Cl 1 plate can choose normalizing and tempering or normalizing and rapid cooling and tempering.

Based on the main SA514 Gr Q steel material 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 SA514 Gr Q steel material products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Semi-endless rolling technology has three advantages: the SA514 Gr Q steel material product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of SA514 Gr Q steel material etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
