What is the difference between JIS SM490C plates and ordinary strength steel

The company has created a group of professional staff with good market awareness and service spirit. More than 90% of the company's employees have college education and more than 3 years of work experience in the industry. Our company has a group of senior professionals engaged in international cargo transportation. Through the implementation of modern centralized control management of the JIS SM490C plates whole system computer network, we can effectively control and guarantee the daily operation of the JIS SM490C plates. The company is dedicated to provide customers with safe, convenient, economic and thoughtful freight service. The company has always followed the principle of "people-oriented", and created a group of professional staff with good market awareness and service spirit.

JIS SM490C plates Steel Standard: API 5CT Dimension range for casing and tubing: Outside diameter (26.67 to 114.30 mm); wall thickness(2.87 to 9.65 mm). Delivery state: Surface anti-corrosive treatment: bared, oiled, color paint, 3LPE; Tube and casing pipes ends: no swaging, threads and flanges. JIS SM490C plates Tubes testing: All tubing and casing pipes has passed ISO9001:2000 assessment and the API 5CT certification.

High wear resistance: fully automatic CNC stacking equipment, independent of manual JIS SM490C plates welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the JIS SM490C plates hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite JIS SM490C plates wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. JIS SM490C plates, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.

The carbon content of JIS SM490C plates, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.

The company is mainly engaged in JIS SM490C plates steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work JIS SM490C plates together for a better tomorrow.
