High Light High Strength 17-4PH Stainless Steel CoilCorrosion Resistant Precipitation Hardening Stainless Steel CoilAerospace Grade 1.4542 Stainless Steel Coil
1.4542 X5CrNiCuNb16-4 AISI 17-4PH S17400 Precipitation Hardening Stainless Steel Coil
Product Overview

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

Frequently Asked Questions
Q1: What is 1.4542 stainless steel?
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.
