BBN offer steel plates S690QL size list

Cold rolled steel sheet has high strength, high hardness and high surface finish. It is generally thin steel plate and can be used as stamping steel plate. The strength of steel plates S690QL, hot rolled steel plate is relatively low, the surface quality can not match with that of cold rolled steel sheet. But its plasticity is good, and it is generally medium thick steel plate. The price difference between cold rolled steel sheet and hot rolled steel plate has a certain relationship with manufacturers. The quality of steel plate manufactured by different manufacturers is different, and the price is also biased.

Standing at a new historical starting point, we adapt to the requirements of supply side steel plates S690QL structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading steel plates S690QL steel materials supplier.

Try to use steel plates S690QL high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the steel plates S690QL temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

The ability to resist plastic deformation and fracture under the action of external load is called steel plates S690QL strength, and the local resistance of solid materials to external objects such as indentation and scribing is hardness. In the mechanical properties of weathering steel, strength and hardness are related indexes, while plasticity (elongation, reduction of area) and toughness (impact value) are related indexes.

Our quality and service commitment: steel plates S690QL product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
