Specifications and ordering data

Specification

Field	Order reference
Standard	A268 TP410 for general-service tubing if specified
Product or route	Hardenable martensitic stainless, UNS S41000
Critical dimensions and fit	Confirm delivery condition, hardness and finished bore or machining allowance
Supply enquiry	Confirm sizes, lengths, route, documentation and lead time for your order

Dimensions and weight

Illustrative drawing sizes. The bore and mass are calculated from the nominal dimensions. Use the project tolerance and confirm the size and route in the quote.

Tube OD (mm)	Wall (mm)	Nominal bore (mm)	Estimated kg/m at 8,000 kg/m³
19.05	1.65	15.75	0.72
25.4	2	21.40	1.18
38	5	28.00	4.15

Service and pressure basis

Use the approved design code and service conditions. The applicable rating depends on material, temperature, minimum effective wall, joint details and the limits of the connected assembly. A schedule or a hydrostatic test result alone cannot establish an operating pressure.

Reference ASME process piping code B31.3

Ordering guidance

Confirm the 410 specification before quoting

An SS 410 pipe or tube enquiry needs the actual product standard and required material condition. Do not carry over an austenitic pipe specification simply because the item is round stainless steel.

If the item is machined or fabricated after delivery, share any hardness, condition or dimensional tolerances called out by the drawing. Request documentation for the exact form and condition offered before releasing an order.

Buyer’s guide

Specify the condition of 410 hollow products

Start with martensitic stainless and the exact standard

Type 410 (UNS S41000) is a martensitic stainless grade. Mechanical properties and hardness can depend on the supplied condition and any subsequent heat treatment. If a drawing only says “410,” check whether it requires general-service tubing, mechanical hollow stock or a special product specification before requesting a quotation.

Describe the machined or finished part

For a machined sleeve, include the target OD, bore and finished length as well as the minimum material allowance needed before machining. For a finished tube, send the specified OD, wall and tolerances. If hardness limits or a heat-treatment condition are required at delivery, record the units, range and acceptance document on the drawing or order.

Verify the offered form and material record

Specify whether the purchase is for a hollow section or tube. A solid round bar quote uses a different material and manufacturing allowance. Ask the supplier to state the offered condition and applicable material specification, then match the report to the goods on receipt.

Example enquiry

A machinist sourcing 410 sleeve blanks can send the finished OD and bore, minimum cleanup allowance and required hardness at delivery. Quote the blank and the finished sleeve as separate scopes if both are options.

Does a magnet identify 410 tubing?

Magnet response cannot identify the specific alloy or delivery condition. Check material markings and the certificate, then use any verification method specified by the project.

Prepare your enquiry

What to put on the purchase list

Item	What to send
Product details	410 · product standard · condition · hardness if specified · dimensions
Delivery	Quantity with units, delivery city and required date if known
Acceptance	Required certificates and inspection scope; attach the drawing revision where applicable

Is every round 410 product a pipe or tube?

No. State that you require a hollow product and give both outside dimensions and wall or bore.
