1.4845 material equivalent

What is en1.4845 material ?

EN 1.4845 is an austenitic stainless steel, also known as AISI 310S, a heat-resistant alloy with high chromium (around 25%) and nickel (around 20.5%) content, making it excellent for high-temperature applications up to 1050°C, offering good resistance to scaling and oxidation, and suitable for welding and forming.

What is the density of 1.4845?

The number 1.4845 refers to a grade of stainless steel (AISI 310S), not a material with a single density value; its density is consistently around 7.9 g/cm³ (or 7900 kg/m³), but slight variations exist (e.g., 7.75 to 8.0 g/cm³), depending on the manufacturer and specific alloy composition.

What is the maximum temperature limit for 1.4845 stainless steel?

1.4845 stainless steel (AISI 310) offers excellent high-temperature performance, with a maximum continuous service temperature generally around 1050°C (1922°F) in air, though peak temperatures can reach up to 1100°C (2012°F) for short durations, depending on the atmosphere and sulfur content, providing resistance to scaling and oxidation.

Is 1.4845 stainless steel magnetic?

No, 1.4845 stainless steel (also known as AISI 310S) is fundamentally non-magnetic because of its austenitic structure, offering excellent high-temperature strength and scaling resistance, but it can become weakly magnetic if heavily cold-worked (like bent or formed).

 

Applications of Grade 310/310S Stainless Steel
Typical Applications Grade 310/310S is used in fluidised bed combustors, kilns, radiant tubes, tube hangers for petroleum refining and steam boilers, coal gasifier internal components, lead pots, thermowells, refractory anchor bolts, burners and combustion chambers, retorts, muffles, annealing covers, saggers, food processing equipment, cryogenic structures.

 

What is the difference between 1.4842 and 1.4825?

Both 310 and 310S are 25Cr-20Ni high chromium nickel austenitic stainless steels. The main difference lies in the carbon content (310≤0.25%, 310S≤0.08%). 310S has significantly improved high-temperature intergranular corrosion resistance and weldability due to its low carbon characteristics, and is more suitable for high-temperature equipment such as industrial furnace components that require frequent welding; 310 has slightly higher room temperature strength in non-welding scenarios due to its higher carbon content. Both can exhibit excellent oxidation resistance above 1000℃.
