Sheet Steel 45 48Mm Asta A366 Astm A569 Price Per Pound

We have factories that can process carbon steel plates with uncoiling, cutting and other production line equipment. Fulfilling orders according to customer needs is the core criterion for us to be able to do business with customers for a long time. The advantages of our products are that there are no burrs on the cutting edge, the surface is smooth, the steel plates of different thicknesses can be cut, and the processing output is stable. Domestic steel prices in China fluctuate, sometimes the price is very high, sometimes the price is very low, and sometimes the price is stable. Welcome customers to consult our sales at any time to get the most affordable purchase price.

Carbon steel plates have usually been considered as the steel that does not contain much alloy steel elements. Generally elements are C, Mn, P, S, Si. What is usually true of carbon steel’s chemical composition is that the manganese won’t exceed 1.65%, the copper hovers between 0.4% and 0.6%, and the silicon won’t exceed 0.6%.

There are three types of carbon steel: low, medium, and high carbon steel. Generally, the higher the carbon content, the stronger and more durable the plate is, but also less ductile and weldable. Low carbon steel is sometimes known as “mild steel” and contains between 0.04% and 0.30% carbon. Medium carbon steel ranges in carbon content from 0.31% to 0.60% and manganese content from 0.060% to 1.65%. While it is stronger than low carbon steel, it is more difficult to weld, form, and cut. You’ll frequently see medium carbon steels hardened and tempered with heat treatment. High carbon steel is also called “carbon tool steel” and ranges in carbon content from 0.61% to 1.50%.

Carbon steel plates are divided into cold-rolled carbon steel plates and hot-rolled carbon steel plates according to the production process.

1> The production process of hot-rolled mild steel plate is to use a rolling mill to roll the steel billet at high temperature. The production process includes: first heating the steel billet, followed by rolling, cooling and grinding. Hot-rolled carbon steel is steel that has been rolled at temperatures exceeding 1,700 degrees. It starts with a large rectangular piece of metal, called a billet. The billets are heated and then sent to preprocessing where they are flattened into large rolls. From there, it is kept at high temperatures and passed through a series of rollers to reach its final size. Steel shrinks slightly as it cools. Because hot-rolled steel is cooled after processing, there is less control over its final shape, making it less suitable for precision applications. Hot rolled steel is commonly used in ships, bridges, pressure vessels, construction, etc.

2> Cold-rolled ms steel plate is a plate obtained by rolling a slab using a rolling mill. The production process includes: first heating the steel billet to a moderate temperature, and then rolling and stretching it. Cold plates have high surface precision, high hardness, and good corrosion resistance. They are usually used to manufacture containers, pipes, etc.

3> cr steel or hr steel decoiling and cutting etc production line FYI

Q: How do you ensure the quality of your products to meet customer needs?
Our boss has more than 10 years of domestic trade experience in different types of steel industry, our foreign trade manager is very familiar with the requirements of different types of steel under different international standards, the steel mills we work with are very famous, stable and they have complete quality management system. and SGS inspection is also no problem. If the customer finds quality problems after receiving the goods, we will pay the customer without hesitation.

Q: Why is the price of the steel on alibaba sometimes inconsistent with the price in the Chinese domestic market?
Steel prices in China's domestic market are higher for a period of time and lower for a period of time. We sincerely recommend that customers consult us at any time to get the lowest price for themselves, it will save buyers' lots of money.
