Resistance overview

SS 304 maintains a consistent rating of D across all 2 tested concentrations (aqueous, saturated) of Tin(II) Chloride at 20 °C. The fact that the rating does not change with concentration within the tested range simplifies material selection, though the boundary conditions beyond this range remain untested. The rating remains stable between 20 °C and 50 °C, which means this material can also handle moderately elevated process temperatures without additional risk.

Application context

Tin(II) Chloride is commonly encountered in pulp and paper and waste treatment. SS 304 (Stainless steel 1.4301 (AISI 304)) is a metal typically used for vessels, heat exchangers, fittings and structural components. Because Tin(II) Chloride is classified as corrosive, the choice of containment material is especially critical to prevent leaks, equipment damage, and safety hazards.

Practical recommendation

SS 304 is not recommended for use with Tin(II) Chloride. The D rating indicates that the material will suffer rapid and severe degradation, which may include cracking, dissolution, severe swelling, or complete structural failure. Using this combination risks equipment damage, leaks, and potential safety incidents. Consider using HDPE, LDPE, Polycarbonate instead, which are rated A for this chemical and offer reliable long-term performance.

Did you know?

When choosing between metals for Tin(II) Chloride service, engineers consider not just the resistance rating but also factors such as permeation rate, creep resistance, and weldability.

About SS 304

Stainless steel 304 (1.4301) resists oxidising acids and most organic chemicals. Chlorides cause pitting and stress-corrosion cracking.

Rating scale

A rating marked * is an estimate in the source, not a test result. An estimate is given as one value without a temperature.

About this data

The ratings come from the chemical resistance list published by Bürkle GmbH, which compiled them from raw-material manufacturers’ data. They describe laboratory tests on the raw material at 20 °C and 50 °C.

A finished part also sees pressure, mechanical stress, welds and mixtures that a laboratory test does not. Treat the rating as a first filter and test under your own conditions before relying on it.
