What is the difference between 309 and 310 stainless?

SS309 is a highly alloyed austenitic stainless steel used for its excellent oxidation resistance, high-temperature strength and creep resistance. The lower nickel content of SS309 compared to SS310 improves resistance to hydrogen sulfide (H2S) attack at high temperatures.

What is type 310 stainless steel?

Grade 310 is a medium carbon austenitic stainless steel, for high temperature applications such as furnace parts and heat treatment equipment. It is used at temperatures up to 1150°C in continuous service, and 1035°C in intermittent service. Grade 310S is a low carbon version of grade 310.

What is difference between SS 310 and ss310s?

Type 310S Stainless Steel is identical to Type 310 except for a lower carbon content that minimizes carbide precipitation and improves weldability. They are essentially nonmagnetic as annealed and become lightly magnetic when cold worked.

What are 309 stainless steels used for?

Type 309 is employed for parts requiring both corrosion and heat resistance and oxidation resistance up to 2000 °F. Strength at elevated temperatures is similar to that of 18-8 Stainless Steels. This alloy posses excellent resistance to oxidation as well as high tensile and creep strengths at elevated temperatures.

What is the difference between SS 304 and SS 310?

1) Composition: 310 type has a higher chromium content (24-26%) vs 304 (10-20%), and nickel content(19-22%) vs 304 (8-10.5%). 2) 304 steel is going to be pretty ductile, and 310 is a bit harder. 3) Stainless steel 310 has greater hardenability, wear and corrosion resistance than 304.

What is the difference between 304 and 309 stainless steel?

Alloy 309/309S is an austenitic heat resisting stainless steel. 23% chromium, approx. 5% more than 304 stainless steel gives Alloy 309/309S an edge over 304 stainless steel when it comes to general corrosion resistance at elevated temperatures.

What is the difference between 304 and 310 stainless steel?

Does 309 stainless steel rust?

The alloy is prone to intergranular corrosion after long term exposure at high temperatures. However, due to its high chromium content (23%), Alloy 309 is more corrosion resistant than most heat resistant alloys.

Is 304 or 310 stainless better?

What is 310 welding rod used for?

Tech-Rod® 310 electrodes are used for welding stainless steels of similar composition in cast and wrought forms. The weld deposit is fully austenitic, and as such, calls for minimal heat input during welding.

Is 310 stainless magnetic?

Type 310 is non-magnetic in the annealed and cold worked conditions and is as resistant to corrosion as Type 304/304L. Mechanical property requirements for annealed product as specified in ASTM A167.

What is the composition of 309 stainless steel?

What is a 310 16 welding rod?

E310-16 electrodes are used to weld stainless steels of similar composition in wrought and cast form. It provides you with outstanding performance for the out-of-position welding of 310 type stainless steels, especially when ease of execution and fine weld appearance are required.

What is the difference between AISI 309 and 310 stainless steel?

AISI 309 Stainless Steel vs. AISI 310 Stainless Steel Both AISI 309 stainless steel and AISI 310 stainless steel are iron alloys. They have a moderately high 91% of their average alloy composition in common. For each property being compared, the top bar is AISI 309 stainless steel and the bottom bar is AISI 310 stainless steel.

What is 309 stainless steel used for?

Alloy 309/309S (UNS S30900/S30908) austenitic stainless steel is typically used for elevated temperature applications. Its high chromium and nickel content provides comparable corrosion resistance, superior resistance to oxidation, and the retention of a larger fraction of room temperature strength than the common austenitic Alloy 304.

What is the difference between CS 309 and CS 309s?

CS 309S is the low-carbon version of CS 309, and is recommended for applications where sensitisation, and subsequent corrosion by high temperature gases or condensates during shutdown may pose a problem. CS 309 is manufactured to ASTM A 167 and CS 309S to ASTM A240 specifications.

What is the difference between alloy 309 and 309s?

Due to their high chromium and nickel content, Alloys 309 and 309S are highly corrosion resistant, have outstanding resistance to oxidation, and excellent heat resistance while providing good strength at room and elevated temperatures. The only significant difference between 309 and 309S is the carbon content.
