Description

2507 stainless steel sheets and plate

2507 stainless steel sheets and plate is composed of 25% chromium, 4% molybdenum, and 7% nickel. It is ferritic-austenitic (duplex) stainless steel. It combines the most beneficial properties of many ferritic sheets of steel and austenitic steel. The steel has a high content of chromium and molybdenum, so it has excellent resistance to pitting corrosion, crevice corrosion, and uniform corrosion. The dual-phase microstructure ensures that the steel has a high resistance to stress corrosion cracking, and the mechanical intensity is also high.

Product Introduction

2507 stainless steel sheets and plate has the following performance characteristics:

Resistance to pitting, crevice corrosion, and uniform corrosion; Resistance to stress corrosion cracking, high mechanical strength.

Grade 316L can not be used in the hydrochloric acid environment, it may suffer local corrosion or overall corrosion. 2507 (S32750) can be used in diluted hydrochloric acid environments, with strong resistance to spot damage and crevice corrosion.

The duplex structure of 2507 (S32750) gives it strong resistance to stress corrosion cracking. Due to its higher alloy content, the corrosion resistance and strength of 2507 (S32750) are better than 2205.

Mechanical characteristics: 2507 (S32750) has high compressive strength, impact strength, low thermal expansion coefficient, and high thermal conductivity. These characteristics are suitable for many structural parts and mechanical parts
