1.4057 Stainless Steel
All You Need to Know About Martensitic, Highly Corrosion Resistant Stainless Steel X17CrNi16-2, 1.4057, SS2321, ASTM 431
What is 1.4057 Stainless Steel Grade
The 1.4057-grade stainless steel is martensitic steel with high tensile strength. It also good machinability and is weldable. If you are looking for corrosion-resistant steel which is resistive to strong oxidizing acids, e.g. nitric acid, 1.4057 stainless steel grade will be perfect.
The 1.4057-grade stainless steel has the following properties:
- Good corrosion resistance
- High tensile strength
- Resistant to strong oxidizing acids
Why use 1.4057 Stainless Steel
First of all, the 1.4057- stainless steel grade comes with good machinability and tensile strength which can be utilized to a great extend. Moreover, the stainless steel grade is weldable and is easier to machine than conventional austenitic steel grades.
The steel is also magnetic under certain conditions.
