SA709 Gr 50 carbon steel plate sheet top manufacturer in Thailand

Since it was established in 2000. Based on the domestic rich SA709 Gr 50 carbon steel plate sheet product resources and the great steel demand of the international market, our SA709 Gr 50 carbon steel plate sheet service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver SA709 Gr 50 carbon steel plate sheet goods in time and smoothly. At the same time, because of the long-term cooperation and huge shipping volume, we can get a good transportation price and save transportation cost for the company and customers. Meanwhile, we have Shipping Department to arrange shipping work in advance. So as not to waste time on transportation both in land and on the sea.

Hydrogen (H) is the most harmful element in general steel such as SA709 Gr 50 carbon steel plate sheet. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the SA709 Gr 50 carbon steel plate sheet steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
