Stainless Steel 310 Pipes
Stainless Steel 310 pipes are high-alloy austenitic pipes designed for extreme temperature service. It is also referred to as SS 310 or UNS S31000 pipes. The material contains high 24–26% chromium and 19–22% nickel, which improve oxidation and corrosion resistance. Alloy 310 is used in heat-intensive systems where strength must stay stable. SS 310 has three main benefits: it handles high heat well, is easy to weld, and lasts a long time. It is commonly used in furnaces, heat exchangers, and chemical plants where equipment withstands high temperatures.
310 Stainless Steel Pipe Price
SS 310 pipe is a high-temperature grade; it often costs more than standard stainless steel pipes. In India, prices vary according to pipe size, thickness, and market conditions.
Approximate Price Range
In most cases, 310 stainless steel pipes are priced between ₹500 and ₹900 per kg. Thin pipes may fall on the lower side, while heavy or larger diameters go higher.
Factors Affecting Price
Nickel and chromium content have a direct impact on the price, as the 310 grade contains higher alloy levels. Size, wall thickness, and surface finish also affect the cost. Seamless pipes are generally more expensive than welded ones. Changes in raw material cost and market demand can lead to regular price fluctuations.

How To Choose The Right 310 Stainless Steel Pipe Suppliers
Choosing the right SS 310 pipe supplier affects product quality, delivery timelines, and overall project cost. Evaluate any potential supplier on these 6 parameters before placing an order.
- Evaluate the manufacturer's technical expertise: The 310 stainless steel pipe manufacturer understands material grades, heat treatment processes, and pressure ratings. Ask for documented case studies or project references specific to SS 310 applications.
- Check grade availability and product range: A reliable supplier stocks SS 310 in all pipe types, such as seamless, EFW, ERW, and fabricated forms. Limited availability often leads to delays or substitution with inferior grades.
- Verify quality certifications and testing capabilities: Look for ISO 9001, PED, and mill test certificates that meet EN 10204 3.1 or 3.2 criteria. In-house tests that can ensure quality control include hydrostatic, PMI, and ultrasonic testing.
- Examine the strength of raw material sourcing: Suppliers who source billets and coils from certified primary mills maintain consistent alloy composition. Ask for mill heat numbers traceable to original melt records.
- Assess customisation capabilities: Certain projects require special sizes and finishes. Check if the supplier can provide cut-to-length pipes, exact diameters, and custom thickness with timely delivery.
- Review delivery timelines and supply capacity: A supplier who maintains stock inventory and conducts in-house processing reduces lead time concerns to meet urgent shipment requirements.

Stainless Steel 310 Pipes FAQ's
The prices of SS 310 pipes in India vary between ₹500 and ₹900 per kg, based on pipe type, size, wall thickness, finish, and order quantity. Seamless pipes are more expensive than welded variants.
Grade 310 is a high-alloy austenitic stainless steel with 24–26% chromium and 19–22% nickel. It is classified under ASTM A312 and ASME SA312 standards. The grade is specifically designed for continuous high-temperature service up to 1150°C and intermittent use up to 1035°C.
SS 310 outperforms SS 304 in high-temperature and oxidation-resistant applications. SS 310 contains approximately double the chromium and 10% more nickel than SS 304. For standard corrosion resistance and structural applications below 700°C, SS 304 works well and is more cost-effective. For furnace parts, heating equipment, and other high-temperature uses, SS 310 is the better choice.
SS 310 pipes contain a maximum of 0.25% carbon, 2.0% manganese, 1.50% silicon, 0.045% phosphorus, 0.030% sulphur, 24–26% chromium, and 19–22% nickel. There is no specified molybdenum or nitrogen content in the standard 310 grade. This composition provides the alloy with its signature heat and oxidation resistance.
