JIS SM490YB plates Typical Application

Both 20# seamless steel pipe and 20G seamless steel pipe are carbon structural steel with average carbon content of 0.20%. There are big differences in the use standard, chemical composition, mechanical properties and price between JIS SM490YB plates, 20# seamless steel pipe and 20G seamless steel pipe, so they must be selected correctly in the design and use, so as to avoid affecting the service life or even causing destructive accidents. The purpose of JIS SM490YB plates, GB8162 20# seamless steel pipe is for general structure, the purpose of GB8163 20# seamless steel pipe is for conveying fluid, and the purpose of GB3087 standard 20# seamless steel pipe is for low and medium pressure boiler. 20G seamless steel pipe is used for high pressure steam boiler and pipeline.

The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy JIS SM490YB plates products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of JIS SM490YB plates stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick JIS SM490YB plates steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

Chromium element (Cr element) can improve the strength and hardness of JIS SM490YB plates, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
