The molybdenum stabilizes the passive film against chloride pitting, making 316 the standard step up from 304 for marine atmospheres, brackish cooling water, and chemical process streams. The L grade limits carbon for weldability. ## Chemical composition, 316L | Element | Requirement | | --- | --- | | Carbon | 0.035% max | | Chromium | 16.0 to 18.0% | | Nickel | 10.0 to 14.0% | | Molybdenum | 2.00 to 3.00% | | Manganese | 2.00% max | ## Mechanical properties | Property | 316 | 316L | | --- | --- | --- | | Tensile strength, min | 75,000 psi | 70,000 psi | | Yield strength, min | 30,000 psi | 25,000 psi | | Elongation in 2", min | 35% | 35% | ## Where it is used - Heat exchangers on brackish or treated cooling water. - Chemical process exchangers handling organic acids, phosphoric acid, and chlorinated streams. - Marine and offshore instrumentation and process tube. - Pharmaceutical and food processing where 304 has pitted. ## Beyond 316L Seawater, hot chloride brines, or chloride stress corrosion cracking risk: SA789 duplex, C70600 copper-nickel, or the nickel alloys. We quote all of them from the same desk. **What to put in your TP316 / 316L RFQ** Seamless or welded, OD, wall, length or U-bend schedule, quantity, finish, PMI requirement, and the chloride level or process fluid so we can confirm 316L is adequate or suggest duplex. ### Documents - [Ameritube main brochure](https://ameritube.net/hubfs/PDFs/main_brochure.pdf?hsLang=en)PDF - [ISO 9001:2015 certificate](https://ameritube.net/hubfs/PDFs/ISO_CERT.pdf?hsLang=en)PDF ### Related alloys [C44300](https://ameritube.net/products/c44300-admiralty-brass?hsLang=en)[C70600](https://ameritube.net/products/c70600-copper-nickel-90-10?hsLang=en)[C71500](https://ameritube.net/products/c71500-copper-nickel-70-30?hsLang=en)[C72200](https://ameritube.net/products/c72200-copper-nickel-chromium?hsLang=en)[SA179](https://ameritube.net/products/sa-179?hsLang=en)[SA213 T5](https://ameritube.net/products/sa213-t5?hsLang=en) ### Industries [Marine & Defense](https://ameritube.net/markets/marine?hsLang=en)[Oil & Gas](https://ameritube.net/markets/oil-gas?hsLang=en)[Chemical Processing](https://ameritube.net/markets/chemical?hsLang=en) Alloy: TP316 / 316L Stainless Steel × Copper & Brass (Made in USA) **C12200**DHP Copper **C44300**Admiralty Brass **C70600**Copper Nickel 90/10 **C71500**Copper Nickel 70/30 **C72200**Copper Nickel Chromium Carbon & Alloy Steel **SA179**Seamless Carbon Steel **SA213 T2**Alloy Steel Boiler Tube **SA213 T5**Alloy Steel Boiler Tube **SA213 T9**Alloy Steel Boiler Tube **SA213 T11**Alloy Steel Boiler Tube **SA213 T12**Alloy Steel Boiler Tube **SA213 T22**Alloy Steel Boiler Tube Stainless & Duplex **TP304 / 304L**Stainless Steel **TP316 / 316L**Stainless Steel **TP321 / 321H**Stainless Steel **TP347 / 347H**Stainless Steel **SA268**Ferritic Stainless **SA249**Welded Stainless **SA789 S32205 / S31803**Duplex Stainless Nickel Alloys **Alloy 200**Nickel 200 (N02200) **Alloy 276**C-276 (N10276) **Monel 400**Nickel Copper (N04400) **Monel 405**Free-Machining Nickel Copper (N04405) **Alloy 600**Inconel 600 (N06600) **Alloy 625**Inconel 625 (N06625) **Alloy 800**Incoloy 800 (N08800) **Alloy 825**Incoloy 825 (N08825) Not sure? **Ask us**Describe the service and we will recommend the alloy No match.
