S450J0 carbon steel plate sheet main application data

ASTM A387 steel is the standard specification for pressure vessel plates, alloy steel, chromium-molybdenum. Plates under this standard Hebei Metals supplies include ASTM A387 Grades 2, S450J0 carbon steel plate sheet Grade 12, Grade 11, Grade 22, Grade 22L, Grade 21, Grade 21L, Grade 5, Grade 9, Grade 91. Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength levels. These Cr-Mo A387 alloy steel is primarily manufactured for welded boilers and pressure vessels for elevated temperature service.

The company is based on the principle of good faith, small profits and quick sales, and keeps forging ahead. In the fierce market competition, with S450J0 carbon steel plate sheet good cooperation and sincere service spirit, we win the trust of our customers and develop rapidly. We will create a win-win situation with our customers and create a better future with the belief of pioneering, pursuing excellence and learning.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized S450J0 carbon steel plate sheet are higher than that of annealed S450J0 carbon steel plate sheet, but the elimination of internal stress is not as good as annealing. The normalizing operation of S450J0 carbon steel plate sheet is simple, the cost is low, the productivity is high, and it is widely used in actual production.

30CrMnSiA steel delivery status: S450J0 carbon steel plate sheet, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.

It is very important for a company to have a sound after-sales service system, which better guarantees the interests of customers and increases the reliability of the company's products in the hearts of customers. Our company has a dedicated after-sales service team and good after-sales service reputation, and has been recognized by customers over the past decades. Whenever there is problem about our S450J0 carbon steel plate sheet steel materials during application on the user site, our after-sales service persons will assist to find solutions at the first time.
