In the domain of high-temperature industrial applications, Grade 310S (UNS S31008) remains the superior choice due to its exceptional resistance to oxidation and corrosion at temperatures up to 1150℃.
However, due to its high alloy content, pricing for 310S components is significantly more volatile than standard austenitic grades like 304 or 316.3+1This report outlines the current pricing structure for 310S Stainless Steel Forged Elbows, manufactured strictly in accordance with ASME B16.11, covering both Socket Weld (SW) and Threaded (NPT/BSP) types.
Why 310S Is So High?
To understand the price tag of a 310S forged elbow, one must analyze the metallurgy and the manufacturing standard.
Alloy Surcharge: 310S contains roughly double the Nickel and Chromium of 304 stainless steel. As the London Metal Exchange prices for Nickel fluctuate, the base cost of 310S shifts almost immediately.
Forging vs. Casting:
ASME B16.11 requires forged steel. Forging produces a denser, stronger grain structure than casting, essential for high-pressure systems (3000LB, 6000LB, 9000LB). This process is energy-intensive and requires higher labor costs, contributing to the final price.
Carbon Control:
The "S" in 310S denotes lower carbon, which minimizes carbide precipitation during welding. This additional refining step adds a marginal cost over standard 310 but is non-negotiable for weld integrity in critical heat exchangers and furnace parts.
Pricing: ASME B16.11 Forged Elbows (90°)
The following pricing is based on current Q1 2026 factory ex-works estimates. These figures refer to Class 3000 and Class 6000 ratings, which are the industry standards for high-pressure piping.
Material: ASTM A182 F310S

Pricing Nuances:
Quantity: Orders exceeding 500 pieces typically trigger a volume discount of 3-5%.
Testing: Prices above include standard chemical and mechanical testing (MTC EN 10204 3.1). Additional testing (e.g., Ultrasonic, PMI, or Third-Party Inspection like SGS/BV) will incur additional fees.
310s Stainless Steel Forged Elbow Procurement Strategy
When sourcing 310S forged elbows, low price often signals low quality or material substitution. To protect your supply chain:
Demand MTCs: Always require a Mill Test Certificate (EN 10204 3.1) verifying the chemical composition.
Verify Dimensions: Ensure wall thickness meets ASME B16.11 requirements. Under-dimensioned fittings are a common cost-cutting tactic in lower-tier markets.
Lock in Pricing: Due to Nickel volatility, price validity is usually limited to 3-7 days. If you have a large project, ask for a forward contract to lock in raw material rates.
As a factory, we focus on rigorous adherence to the ASTM A182 and ASME B16.11 standards to ensure that every elbow can withstand the pressures and temperatures it was designed for.
