What is the difference between Q690C carbon steel plate sheet and ordinary strength steel

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of Q690C carbon steel plate sheet. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.

Ordinary carbon structural steel Q690C carbon steel plate sheet has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.

Common medium thick and heavy steel plates are widely used for manufacturing various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low steel alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile girder steel plates, tractor parts and welding components. Q690C carbon steel plate sheet, bridge steel plates are used for large railway bridges. They are required to bear dynamic load, impact, vibration, corrosion resistance, etc.

India's Ministry of Q690C carbon steel plate sheet steel has extended the deadline for steel product certification from April 23 to three months as the Bureau of standards (BIS) has closed factories and laboratories due to the current blockade and travel ban. According to the order of the Ministry of Commerce, "the implementation date of the following Indian Standards is extended for three months after April 23, according to the notice of the order for Q690C carbon steel plate sheet steel products 2000."
