2507 is a brand 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 industry and subsea equipment.

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

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

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

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