SAE 9260 is a spring steel with 0.56–0.64% carbon, 1.80–2.20% silicon and 0.75–1.00% manganese, and no chromium. The high silicon gives high yield strength and good resistance to set. It is used for leaf springs, coil springs, rail clips and fasteners, torsion bars and heavy vehicle springs.
OneKaizen supplies SAE 9260 as hot-rolled steel in 2–16 mm thickness and 900–2,900 mm width, round bars in Ø 16–500 mm, bright bars in Ø 8–160 mm and wire rods in Ø 5.5–40 mm, sourced from Indian and international mills. Delivery condition is your choice: hot rolled, annealed, or quenched and tempered. Every consignment ships with a mill test certificate.

Delivery Condition and Heat Treatment
Springs from SAE 9260 are normally formed hot, then quenched in oil and tempered to the hardness your drawing requires. Without chromium, the steel has lower hardenability than SAE 9254, so it suits leaf and coil springs of moderate section. For thick sections, consider a chromium grade such as SAE 5160.
High silicon steels decarburise easily at the surface during hot rolling and heat treatment, and a decarburised surface cuts fatigue life. State the permitted decarburisation depth in your order. Shot peening after forming improves fatigue life.
Welding is not recommended. The high carbon and silicon make the weld zone hard and brittle, and a welded spring loses its fatigue strength.

SAE 9260 Questions
Is SAE 9260 the same as SUP7?
JIS SUP7 is a direct equivalent, with the same carbon and silicon bands. The manganese minimum differs slightly (0.70% in SUP7), and the phosphorus and sulphur limits can differ. Tell us if your drawing needs the exact SAE chemistry.
Is SAE 9260 the same as 60Si7 or 60Si2Mn?
They are close but not identical. 60Si7 and GB 60Si2Mn are widely supplied against SAE 9260 orders, but their silicon bands are lower (about 1.50–2.00%). Check your drawing before accepting a substitute.
What is the difference between SAE 9260 and SAE 9254?
SAE 9254 has less silicon (1.20–1.60%) and adds 0.60–0.80% chromium. The chromium gives better hardenability and temper resistance, so SAE 9254 is used for valve springs. SAE 9260 is the usual choice for leaf and coil springs.
Can SAE 9260 be heat treated or welded?
Yes, it is quenched and tempered to make springs. We do not recommend welding.
What is SAE 9260 used for?
Leaf springs, coil springs, rail clips and fasteners, torsion bars and heavy vehicle springs, mainly for automotive, railway, commercial vehicle and agricultural equipment. OneKaizen also machines parts to drawing through partner machine shops.
What is the minimum order for SAE 9260?
3 tonnes, flexible depending on size and your situation. Send us your size, condition and quantity and we confirm availability and delivery.
What is SAE 9260 equivalent to?
SAE 9260 is the same grade as AISI/SAE 9260, UNS G92600, JIS SUP7, UNI 60Si7. Close equivalents are EN 60Si7, GB 60Si2Mn.
In which forms do you supply SAE 9260?
OneKaizen supplies SAE 9260 as Hot Rolled Steel, Round Bars, Bright Bars, Wire Rods, delivered across India and exported to buyers abroad.
Do you supply SAE 9260 with a mill test certificate?
Yes. Every lot ships with an EN 10204 3.1 mill test certificate showing chemistry and mechanical properties, traceable to the heat number.
