1.4542 X5CrNiCuNb16-4 AISI 17-4PH S17400 Stainless Steel Coil is a premium precipitation hardening stainless steel product designed for applications requiring a combination of high strength, excellent corrosion resistance, superior hardness, and good fabrication performance.
Also known as 17-4PH Stainless Steel, this grade belongs to martensitic precipitation-hardening stainless steels. It achieves extremely high mechanical strength through heat treatment while maintaining corrosion resistance comparable to conventional stainless steels such as AISI 304.
Key Applications
Aerospace engineering
Oil and gas equipment
Marine engineering
Chemical processing
Nuclear power systems
Pressure equipment
High-performance machinery
Main Advantages
High tensile strength and hardness
Excellent corrosion resistance
Good weldability
Good machining performance
Excellent resistance to oxidation up to approximately 539°C
Stable performance in fresh water, marine atmosphere, and industrial environments
1.4542 is the European designation for 17-4PH stainless steel, also known as AISI S17400. It is a precipitation-hardening stainless steel with high strength, excellent corrosion resistance, and good fabrication performance.
Q2: What is the difference between 17-4PH and normal stainless steel?
Compared with conventional stainless steels such as 304 or 316, 17-4PH provides significantly higher strength and hardness through precipitation hardening while maintaining good corrosion resistance.
Q3: Can 17-4PH stainless steel be welded?
Yes. 17-4PH can be welded using shielded fusion welding and resistance welding processes. AWS E/ER630 filler materials are recommended when matching base metal properties are required.
Q4: What industries use 17-4PH stainless steel?
17-4PH stainless steel is widely used in aerospace, oil and gas, marine engineering, chemical processing, nuclear power, and high-performance machinery.
Q5: What certificates are available for 1.4542 stainless steel coil?
We provide ISO9001 quality certification, Mill Test Certificate (MTC), and third-party inspection reports such as TUV, CE, SGS, and other certifications upon request.
