A516Gr.65material is a carbon steel plate for medium and low temperature pressure vessels, which implements the ASTM A516 standard of the American Standard. The BV DH40 oil carrier steel) product minimum thickness that can be provided is 8mm and the width is 1500~4000mm. It has sufficient strength and toughness, good welding performance and hot and cold processing performance. A516Gr.65 steel plate can be used to manufacture pressure vessel steel for petrochemical, gas separation and gas storage, oil storage tank and transportation equipment.
The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel BV DH40 oil carrier steel products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our BV DH40 oil carrier steel business. We also provide third-party inspection and approval services and inventory management for our customers.
The main applications of normalizing are as follows:① For low carbon steel, BV DH40 oil carrier steel. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of BV DH40 oil carrier steel etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in BV DH40 oil carrier steel etc. steel is strictly controlled.
When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
