Step 1: Define the buyer's constraints before asking for a price

A useful request for quotation starts with the job, not the electrode. Before comparing any stainless steel electrode price, write down:

• Base metal grade to be welded (for example, a Mo-bearing stainless steel versus a Ti-stabilized grade).
• Service environment of the finished equipment, such as the type of corrosive medium.
• Electrode diameters your welders need for the joint thicknesses involved.
• Available welding current (AC, DC or both) on site.
• Required deposited-metal properties, including minimum tensile strength and elongation, and any chemistry limits in your project specification.
• Commercial and documentation needs: quantity, packing, delivery destination and any certificates your project requires. You need to confirm these with the supplier because the product pages do not cover them.

If you skip this step, a cheaper quote may simply be for a different classification that does not suit the job.

Step 2: Check the published E316L-16 specification

The manufacturer's product page lists the following for Stainless Steel Electrodes E316L-16:

• Model: CB-A022
• GB / AWS designation: E316L-16 / E316L-16
• Diameter: 2.5 to 5.0 mm
• Type of coating: lime-titania type
• Current: AC, DC
• Stated use: welding equipment for urea, synthetic fiber, etc., and stainless steel structures of the same types

Published deposited-metal chemical composition (%):

• C: max 0.04
• Mn: 0.5 to 2.5
• Si: max 0.90
• S: max 0.030
• P: max 0.040
• Cu: max 0.75
• Ni: 11.0 to 14.0
• Mo: 2.0 to 3.0
• Cr: 17.0 to 20.0

Published deposited-metal mechanical properties: tensile strength (Rm) of at least 490 MPa and elongation (A) of at least 30%.

The product material also says that stainless steel electrodes are divided into chromium and chromium-nickel types, and that both are assessed under GB/T983-1995.

Step 3: Make sure you are comparing like with like

A stainless steel electrode price comparison is only fair when the quotes match on these points:

1. Same AWS/GB classification. E316L-16 and E347-16 are different products with different stated uses, so their quotes should not be treated as interchangeable.
2. Same diameter. Confirm which sizes in the 2.5 to 5.0 mm range each quote covers.
3. Same coating type and current suitability. The E316L-16 is published as lime-titania type for AC and DC.
4. Equivalent deposited-metal limits. Compare the chemistry and mechanical values above with each competing offer's data sheet.
5. Same commercial scope. Packing, quantity, destination and documents all affect a quote. Confirm these in writing.

When E316L-16 does not apply: the E347-16 alternative

The same manufacturer publishes a second, separately documented product, Stainless Steel Electrodes E347-16 (model CB-A132). Its stated use is welding key corrosion-resistant 0Cr19Ni11Ti stainless steel containing Ti stabilizer. Here is how its published data compares with the E316L-16:

• Diameter, coating and current: the same as E316L-16 (2.5 to 5.0 mm, lime-titania type, AC and DC)
• Carbon: max 0.08% (E316L-16: max 0.04%)
• Nickel: 9.0 to 11.0% (E316L-16: 11.0 to 14.0%)
• Molybdenum: max 0.75% (E316L-16: 2.0 to 3.0%)
• Chromium: 18.0 to 21.0% (E316L-16: 17.0 to 20.0%)
• Tensile strength (Rm): at least 520 MPa (E316L-16: at least 490 MPa)
• Elongation (A): at least 25% (E316L-16: at least 30%)

If your base metal is the Ti-stabilized grade named above, the E316L-16 recommendation does not apply, and the E347-16 product page is the relevant reference. For any base metal not named in either stated use, check the match against your welding procedure and project specification, and confirm it with the supplier before ordering.

Welding-process notes from the product material

The manufacturer's material warns that chromium stainless steel generally has poor weldability. It says buyers should pay attention to the welding process, the heat treatment conditions and choosing an appropriate electrode. For chromium-nickel stainless steel electrodes, the E347-16 product description adds this guidance to help prevent intergranular corrosion caused by heating:

• Keep welding current lower, about 20% less than for carbon steel electrodes.
• Do not use a long arc.
• Cool quickly between layers.
• Use a narrow bead.

These notes are not a complete welding procedure. Follow your qualified procedure and the applicable safety rules.

About the related search terms

Buyers often search for stainless steel SMAW electrodes or a TIG electrode for stainless steel alongside price queries. The products described here are coated electrodes with a lime-titania type coating. The confirmed material does not describe TIG consumables, so this guide does not cover TIG selection.

Requesting a quote

When you contact Dingzhou Jinlong Metal Production Co., Ltd. about a stainless steel electrode price, state the classification (E316L-16 or E347-16), the diameters, the quantity, packing needs, the destination and any certification or test documents you need. Ask for these items to be confirmed in writing, because this article does not cover them.
