Martensitic Stainless Steel S17400, a corrosion resistant grade Round bar, Flat bar, Plate S17400 Solution annealed condition, ageing treatment.
UNS S17400 Stainless Steel stockholder and supplier - From State-owned Military Industrial Enterprise LonghaiSteel is manufacturer and supplier of S17400 stainless steel round bar and flat bar. S17400 is a corrosion resistant grade which is soft and ductile in the solution annealed condition. Medium to high strength, good toughness and strength is obtained by the appropriate ageing treatment. As a martensitic precipitation hardening stainless it is characterised by high tensile strength and high yield strength obtained by solution annealing, followed by a single or double low temperature age hardening treatment. S17400 has corrosive properties comparable to 304 austenitic stainless steel in many environments.

| Analysis |
|
| Form of Supply |
S17400 flat bar and round bar is commonly stocked in Condition A and can be cut to your specific requirements. Stocks of S17400 H1150+H1150 are available in round bar. Precision ground bar can be produced and supplied ground to your required tolerances.
|
| Applications |
Commonly used in industries such as offshore, marine, food, paper mills, oil field and aerospace. S17400 is used for components such as fasteners, couplings, screws, bushings, studs, fittings, valve stems, roller, wear rings. |
| Forging |
Heat slowly and uniformly to 1180-1200ºC. Do not forge below 1010ºC. Hold at temperature for one hour prior to forging the component. Cool in air to room temperature. Forged components require solution annealing before any further heat treatment. |
| Corrosion Resistance |
S17400 stainless has very good corrosion resistance properties. Corrosion tests in service have shown good results in all aged conditions. With better corrosion resistance to standard hardenable stainless grades such as 431, 420 and 410. 17-4PH has corrosion resistance comparable to 304 stainless specification. |
| Welding |
S17400 requires similar arc and resistance welding processes to those used on standard specifications of stainless steel. Welding up to 100mm thick can be carried out without the requirement of pre heating due to its low hardness. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding S17400 stainless steel. |
| Machining |
Similar in machining characteristics to 304 and 410 stainless steel specifications. Condition H900 has high hardness and strength which is the most difficult to machine and the machining of this is recommended to be carried out at 60% of the rate which is used for Condition A. |
| Nitriding |
For increase resistance to surface wear, with a slight reduction in corrosion resistance, S17400 can be nitrided. When nitrided at 540ºC an approximate hardness of 64-67 HRc is achievable, with a surface hardness depth of up to 0.15mm. The steel maintains a high core strength. |
| Solution Treatment Typical Properties |
S17400 is commonly supplied in the solution treated condition (Condition A). Heat treated at different temperatures will offer a wide range of properties. (We also hold stock in H1150+H1150).

| Heat Treatment |
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each S17400 steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of S17400 stainless steel. |
