S690QL young modulus wooden box as required

Compared with 12CrMoV steel, S690QL young modulus, 12Cr1MoVR pressure vessel steel has higher oxidation resistance and heat strength. The creep limit of this steel is very close to the endurance strength value, and it has high plasticity under the condition of long-term stretching; the steel has good manufacturability and weldability, but it needs to be preheated to 300 ° C before welding, and the stress needs to be removed after welding deal with.

With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate S690QL young modulus shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than S690QL young modulus. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel S690QL young modulus is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

It is a modern high-tech professional enterprise integrating scientific research, S690QL young modulus production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as S690QL young modulus process technology development, technology transfer and related technical consulting and technical services.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
