17-4 PH stainless steel, also known as 17-4 precipitation-hardening stainless steel, is a versatile and corrosion-resistant metal alloy. It belongs to the martensitic precipitation-hardening stainless steel family and is valued for its high strength, excellent mechanical properties, and good corrosion resistance. 17-4 PH stainless steel finds applications in various industries, including aerospace, defense, oil and gas, and medical.
Material details
17-4 PH stainless steel is a chromium-nickel-copper precipitation-hardening alloy. It contains additions of copper and niobium, which contribute to its precipitation hardening capabilities. This alloy can be heat-treated to achieve different strength levels while maintaining corrosion resistance. 17-4 PH stainless steel exhibits good machinability and can be welded using standard welding techniques.

Please note that flexural strength, flexural modulus, and heat deflection temperature (HDT) are not typically provided for metallic materials like stainless steel, as these properties are more relevant to polymers. The values provided for tensile strength, tensile modulus, and tensile elongation are typical ranges for 17-4 PH stainless steel. The exact values may vary depending on the heat treatment condition and specific grade of the alloy.
