Description

2205 stainless steel sheets and plate

2205 stainless steel sheets and plate is duplex stainless steel composed of 21% chromium, 2.5% molybdenum, and 4.5% nickel nitrogen alloy. It has high strength, good impact toughness, and good overall and local stress corrosion resistance.

Product Introduction

2205 stainless steel sheets and plate Sufficient plasticity. The wall thickness of storage tanks or pressure vessels made of duplex stainless steel is 30-50% less than that of commonly used austenite, which is beneficial to reduce costs. Thermal conductivity is better than austenite, thermal expansion coefficient is smaller than austenite by bai, heat fatigue resistance, added stabilizing element titanium, mechanical properties of the weld.

2205 stainless steel sheets and plates have excellent resistance to stress corrosion cracking. Even duplex stainless steels with low alloy content have a higher resistance to stress corrosion cracking than austenitic stainless steels, especially in environments containing chloride ions. Stress corrosion is a prominent problem that is difficult to solve for ordinary austenitic stainless steel.

The corrosion resistance of 2205 duplex stainless steel, which is commonly used in many media, is better than that of ordinary 316L austenitic stainless steel, while super duplex stainless steel has extremely high corrosion resistance. In some media, such as acetic acid, formic acid, etc. It can replace high-alloy austenitic stainless steels and even corrosion-resistant alloys.

It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content, its wear corrosion resistance and fatigue corrosion resistance are better than austenitic stainless steel.

The linear expansion coefficient of austenitic stainless steel is lower than that of carbon steel. It is suitable for connection with carbon steel and has important engineering significance, such as the production of composite plates or linings.
