ASTM A276 Type 316 Chemical Composition and Grade Equivalents
Type 316 is famous because it is a special marine-grade metal that does not rust easily. It gets this superpower from mixing in a rare element called Molybdenum, which acts like a shield against salt water. The simple tables below show the exact ingredients that make this steel so strong and its common names across the world.
Chemical Composition Weight Percentages
| Chemical Element | Allowed Weight Percentage |
|---|---|
| Molybdenum (Mo) | 2.00% to 3.00% (Stops salt water from rusting it) |
| Chromium (Cr) | 16.00% to 18.00% (Gives the metal basic rust protection) |
| Nickel (Ni) | 10.00% to 14.00% (Makes the steel strong and flexible) |
| Carbon (C) | 0.08% Maximum |
| Manganese (Mn) | 2.00% Maximum |
| Silicon (Si) | 1.00% Maximum |
| Phosphorus (P) | 0.045% Maximum |
| Sulfur (S) | 0.030% Maximum |
Certified Mechanical and Physical Properties
| Technical Property | Value (Minimum Limit) |
|---|---|
| Tensile Strength | 75,000 psi (How much pulling force it can take) |
| Yield Strength | 30,000 psi (When it begins to permanently bend) |
| Elongation Capacity | 40% (How much it can stretch before breaking) |
| Hardness Level | 217 HBW Maximum (How scratch-resistant it is) |
| Metal Density | 8.0 grams per cubic centimeter |
International Grade Equivalents Quick Matrix
| Region / Standard | Equivalent Naming |
|---|---|
| UNS Standard Number | S31600 |
| European Code | 1.4401 / 1.4436 |
| Japanese JIS Code | SUS 316 |
Where These Marine-Grade Square Rods Are Used Most
Many ocean engineering companies buy our solid bars because they hold up perfectly against salty sea water. These heavy bars are used to build boat parts, underwater pumps, and oil drilling platforms. The metal keeps its smooth surface even when hit by waves and wet sea air every day.
Chemical plants use this exact steel to build strong mixing tanks and storage racks. The special mix of elements resists harsh acids, industrial dyes, and strong cleaning liquids used in paper or cloth factories. This keeps your pipes and machinery safe from spring leaks or sudden breaks.
Food and medicine factories also rely on our polished metal rods to keep things clean. The smooth silver surface does not let germs or bacteria hide in tiny cracks and easily handles daily washdowns. This ensures your products stay safe, sterile, and free from any contamination.
Safe Shipping and Packing for Worldwide Delivery
As a major exporter, we ship our 316 square bars safely from the local Mumbai port directly to your business. Our experienced shipping team handles deliveries to clients in the UAE, Saudi Arabia, Oman, and across Southeast Asia. We take care of all the customs paperwork so your order arrives on time without any annoying port delays.
We know that long ocean trips can expose bare metal to wet air and rough handling. To protect your order, we wrap the square rods in heavy waterproof plastic and pack them into strong wooden boxes. This keeps your bars dry, perfectly straight, and scratch-free until they open at your yard.
Our team tracks your shipment from our warehouse floor until it arrives safely at your factory gate. We share live tracking codes with your company so you can check on your metal at any time. This complete transparency helps you plan your work schedule before the delivery truck arrives.
Need to Do Heavy Welding? Try Our Low-Carbon Option instead
When you weld thick metal pieces together using intense heat, standard steel can sometimes get weak or rust right along the welded line. If your project involves a lot of heavy welding, we highly recommend checking out our low-carbon bars. This tiny change in the recipe stops weld decay and keeps your joints super strong.
You can easily add this low-carbon option to your order by talking directly with our Mumbai sales team. Our experts will help you pick the exact metal style so your machines run smoothly without any breakdowns. We make it easy to choose the right materials for your job.
