What is JIS G3125 corrosion resistant steel grade SPA-C equivalent?

Based on the main JIS G3125 corrosion resistant steel grade SPA-C business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel JIS G3125 corrosion resistant steel grade SPA-C products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

JIS G3125 corrosion resistant steel grade SPA-C 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 G3125 corrosion resistant steel grade SPA-C Tubes testing: All tubing and casing pipes has passed ISO9001:2000 assessment and the API 5CT certification.

The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product JIS G3125 corrosion resistant steel grade SPA-C more than 15 years.

The main function of boron in JIS G3125 corrosion resistant steel grade SPA-C and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.

In steel standard JIS G3106, SM570 steel owned the highest yield strength above 460 Mpa, and the tensile strength within 570-720 Mpa. For SM570 steel, the C element content is 0.18%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.035% max, the S element content is 0.035% max. JIS G3125 corrosion resistant steel grade SPA-C, SM570 steel with thickness from 6mm-300mm,width from 1500mm-4000mm,length from 5000-16000mm.

We have a professional production team and high-quality production equipment, and we also have a great JIS G3125 corrosion resistant steel grade SPA-C advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the JIS G3125 corrosion resistant steel grade SPA-C production of high-quality steel plates, steel pipes and other products that meet customer requirements.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel JIS G3125 corrosion resistant steel grade SPA-C products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
