The Difference between 2507 and Stainless Steel 316

2507 is a grade of duplex stainless steel, 2507 super duplex stainless steel is composed of 25% chromium, 4% molybdenum and 7% nickel.
2507 dual-phase steel has strong strength and corrosion resistance, and is mainly used in chemical processing, petrochemical and subsea equipment.

2507 dual-phase steel has strong resistance to chloride corrosion, high thermal conductivity and low thermal expansion coefficient. The higher content of chromium, molybdenum, and nitrogen is its high resistance to pitting, crevice corrosion, and general corrosion.

316L is a grade of austenitic stainless steel. 316L austenitic stainless steel is composed of 16% chromium, 2% molybdenum and 10% nickel.
316L has a wide range of applications in the chemical industry due to its excellent corrosion resistance. 316L is also a derivative of 18-8 type austenitic stainless steel, with 2 to 3% of Mo added.

On the basis of 316L, many steel grades are also derived. For example, 316Ti is derived after adding a small amount of Ti, 316N is derived after adding a small amount of N, and 317L is derived by increasing the content of Ni and Mo.

Due to the influence of the dual-phase structure, 2507 dual-phase steel has the characteristics of austenitic and martensitic stainless steel at the same time. The performance of 2507 dual-phase steel is generally better than that of 316L, and the price is relatively higher.

Sino Stainless Steel is mainly engaged in 2205.2507 and stainless steel materials. Our duplex steel materials have always been cheaper for the same quality.

The quality of materials has always been strictly controlled. Each batch of goods has a quality inspection report and a material certificate. Every process is to deliver products that customers are satisfied with.
