Chemical elements of S690QL plate thickness

The company attaches great importance to systematic management, and has passed the S690QL plate thickness ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on S690QL plate thickness quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Boiler steel plate S690QL plate thickness mainly refers to the hot-rolled medium and heavy plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The main boiler steel materials are high-quality structural steel and low-alloy heat-resistant steel. Common boiler steel includes low-carbon killed steel S690QL plate thickness smelted in open furnace or low-carbon steel smelted in electric furnace, with carbon content WC in the range of 0.16% - 0.26%.

45# steel is commonly used medium carbon quenched and tempered structural steel. The steel S690QL plate thickness is generally cold plastic, annealing and normalizing are slightly better than quenching and tempering, with higher strength and better machinability. After proper heat treatment, 45# carbon steel can certain toughness, plasticity and wear resistance can be obtained. 45# steel normalizing can improve the cutting performance of roughness less than 160HBS.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of S690QL plate thickness structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
