Export great Q235B carbon steel plate sheet to Thailand

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep Q235B carbon steel plate sheet processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and Q235B carbon steel plate sheet steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Most of the Q235B carbon steel plate sheet steel materials used in industrial boilers are carbon steel materials. In a narrow sense, the boiler steel refers to the special steel used for manufacturing industrial boilers and power station boilers, mainly including pressure vessel steel, anti-oxidation steel and hot strength steel. Some of them are carbon steel, most of them are medium and low alloy steel, and a few are high alloy steel Q235B carbon steel plate sheet. In a broad sense, the boiler steel includes all the steel used to manufacture industrial boilers and utility boilers.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. Q235B carbon steel plate sheet, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the Q235B carbon steel plate sheet metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between Q235B carbon steel plate sheet strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
