The gas cylinder steel coil and sheets are our main products. Our main conducted standards for gas cylinder steel coil and sheets are JIS G3116, GB6653, EN10120. The typical gas cylinder steel grades are SG255, SG295, SG325, HP265, HP295, HP325, P245NB, P265NB, P310NB, P355NB, etc. For the gas cylinder steel coil A572 grade 42 CS steel carbon plate, we provide slitting, cutting, and stamping service. So as to meet different size and shape requirements of the customers. The gas cylinder steel coil and sheets are mainly used to make gas cylinders.
In today's A572 grade 42 CS steel carbon plate steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of A572 grade 42 CS steel carbon plate market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.
In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of A572 grade 42 CS steel carbon plate high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Anshan Iron and Steel's 4300 mm rolling mill, Shagang's 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's A572 grade 42 CS steel carbon plate technical equipment.
With the increase of temperature, the yield limit of A572 grade 42 CS steel carbon plate will decrease monotonically, but the tensile strength of A572 grade 42 CS steel carbon plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of A572 grade 42 CS steel carbon plate. Near the blue brittleness temperature, the A572 grade 42 CS steel carbon plate strength increases and the plasticity decreases. The elongation and section shrinkage of A572 grade 42 CS steel carbon plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
