1.4835 vs. 1.4845 Stainless Steel: What the Differences?

What material is equivalent to 1.4835?

Material 1.4835 (X9CrNiSiNCe21-11-2) is a heat-resistant austenitic stainless steel, primarily known by the trade name 253MA and the UNS designation S30815. It is engineered for high-temperature applications up to 1150°C, offering excellent oxidation resistance and high creep strength.

What material grade is 1.4845 equivalent to?

Material grade 1.4845 (also known as EN X8CrNi25-21) is equivalent to AISI 310S. Itis a highly alloyed austenitic stainless steel engineered for superior heat resistance, withthe "S" variant indicating lower carbon (s0.08%) to enhance weldability and corrosionresistance at elevated temperatures up to I 100°C (2012° F).

What is the difference between 1.4835 and 1.4845 stainless steel?

1.4835 (253 MA) and 1.4845 (310S) are both high-temperature austenitic stainlesssteels, but 1.4835 offers superior creep strength and oxidation resistance up to I 100°Cdue to nitrogen and rare earth alloy additions. Conversely, 1.4845 provides bettercorrosion resistance in acidic environments and is used up to 1050"C.

1.4835 (253MA) vs. 1.4845 (310S)：Chemical Composition (%)

1.4835 (253MA) vs. 1.4845 (310S)：Mechanical Properties (at 20°C)

1.4835 (253MA) vs. 1.4845 (310S)： High-Temperature Performance

 1.4835 vs. 1.4845 Stainless Steel: Operating Temperatures

1.4835 (253 MA): Designed for maximum operating temperatures up to 1100°C - 1150°C (2012°F - 2102°F).
1.4845 (310S): Designed for maximum operating temperatures up to 1050°C - 1100°C (1922°F - 2012°F).

1.4835 vs. 1.4845 Stainless Steel:Applications

1.4835: Preferred for high-load applications like furnace components, heat-resistant fasteners, and conveyor belts.
1.4845: Commonly used for burner parts, heat exchangers, and furnace liners where oxidation resistance is paramount.

What is the difference between 1.4404 and 1.4835 material?

1.4404 (AISI 316L) is a corrosion-resistant, low-carbon stainless steel for general, wet, or chemical environments. In contrast, 1.4835 (253 MA) is a heat-resistant austenitic stainless steel designed for high-temperature oxidation resistance, holding superior strength at elevated temperatures. The main difference is usage: 1.4404 is for wet corrosion, 1.4835 for high-heat.

Can 1.4835 (253MA) replace 1.4845 (310S) in high-heat applications?

In many cases, yes. 1.4835 is often used as a cost-effective alternative to 310S because it provides similar oxidation resistance up to 1150°C. However, in highly reducing or carburizing atmospheres, 310S might still perform better due to its higher Nickel content. Always check the specific gas environment before substituting.

Why is 1.4835 often cheaper than 1.4845?

The cost difference is mainly driven by Nickel content. Nickel is a volatile and expensive commodity. Since 1.4835 contains only about 11% Nickel compared to the 20% found in 1.4845, 1.4835 is generally more economical and has more stable pricing.
