1.4845 Stainless Steel

1.4845 is a heat‑resisting stainless steel grade, available in bar, plate and tube, delivered throughout the UK. It offers high resistance to oxidation scaling as well as strong performance at elevated temperatures. Compared to other austenitic stainless steel grades, 1.4845 has significantly better creep strength at high temperatures. Continuous service oxidation resistance extends to approximately 1100 °C.

1.4845 stainless steel is held on stock and can be delivered throughout the UK.  All orders are supplied in accordance with our ISO 9001 accreditation.

Applications

Owing to its excellent heat resistance, 1.4845 is commonly used in furnace parts, heat‑treatment baskets, jigs, case‑hardening boxes, steam‑locomotive components, burners, combustion chambers, heat exchangers, and in food processing equipment.

Carbon 0.15% max Chromium 24.00-26.00%
Manganese 2.00% max Nickel 19.00-22.00%

Molybdenum 1.00% max Phosphorous 0.045% max

1.4845 stainless steel is compatible with most welding techniques. However, oxyacetylene welding is not recommended due to possible uptake of carbon in the weld zone. When filler metal is required, compositions matching the base material are usually used. We advise consultation with your welding consumables supplier for full guidance on welding procedures.

Heat 1.4845 stainless steel slowly and evenly throughout the section to about 1100‑1230 °C. Re‑heat if necessary. Avoid working at temperatures below about 1000 °C. Rapid cooling is essential in order to maximise corrosion resistance. Forged parts will need annealing to reach optimum corrosion resistance.

The “scaling temperature” refers to the temperature at which oxidation rate becomes unacceptably high. For continuous service in oxidising atmospheres, the safe scaling temperature for 1.4845 stainless steel is 1100 °C. In oxidising or reducing sulphurous atmospheres, this temperature is reduced.
