What is the en 1.4501 material?
1.4501 is a high-performance super duplex stainless steel material, also known as UNS S32760, ASTM F55, and sometimes referred to as Zeron 100. This stainless steel is known for its excellent corrosion resistance, high strength, and good weldability. It contains high levels of chromium, molybdenum, and nickel, with the addition of tungsten, giving it superior resistance to pitting and crevice corrosion in chloride-rich environments. It can be processed into various practical product forms, including plates, coils, tubes, bars, and wires.
What material is 1.4501 equivalent to stainless steel?
1.4501 is a super duplex stainless steel, equivalent to UNS S32760 and ASTM A182 F55, commercially known as Zeron 100 or Alloy 32760. Due to its composition containing 25% chromium, nickel, molybdenum, copper, nitrogen, and tungsten, it possesses high strength and excellent corrosion resistance (especially resistance to pitting/stress corrosion cracking).

What is the hardness of 1.4501 stainless steel?
1.4501 stainless steel, a martensitic stainless steel, typically achieves a hardness of ≈48–55 HRC after quenching and tempering, making it suitable for wear-resistant components, shafts, and high-strength mechanical parts.
What is the corrosion resistance of 1.4501 stainless steel?
1.4501 offers moderate corrosion resistance, performing well in atmospheric and mildly corrosive environments, but it is less resistant to chlorides and aggressive acids compared with austenitic or duplex grades like 1.4410, making surface protection or proper selection critical for harsh chemical applications.
Is 1.4501 stainless steel magnetic?
Yes. Being a martensitic stainless steel, 1.4501 is magnetic in both annealed and hardened conditions, which can be advantageous in applications requiring magnetic properties but should be considered for non-magnetic design requirements.
What are the differences between 1.4501 and 1.4410 stainless steel?
1.4501 is a martensitic stainless steel optimized for high hardness, wear resistance, and heat-treatable strength, while 1.4410 is a duplex stainless steel with balanced austenitic-ferritic microstructure, offering better corrosion resistance (especially pitting and crevice corrosion) and higher toughness, but lower hardness. In short, 1.4501 is suited for mechanical, wear-focused applications, whereas 1.4410 is ideal for corrosion-critical and structural applications.
