"In order to maintain the integrity of the stainless steel industry and to ensure that Sassda member companies are not compromising on the quality of imported products, it is important to ask for a test certificate upon receiving the product," says former Sassda MD Michael Campbell.
He adds that the association has been alerted to cases of sub-standard and underspecification stainless steel being imported and sold throughout South Africa.
"The test certificate is the only way to confirm that materials meet international chemical and mechanical specifications. Without this certificate, buyers should be aware that the product they are purchasing will not have a guarantee of origin and as such they will have no recourse should the product fail in any way, or suffer from accelerated corrosion," says Campbell.
He adds that the test certificate should list the dimensions of the product, the grade or type of stainless steel, the heat number, the chemical composition, as well as the mechanical properties of that steel, and be certified by the inspecting authority and/or the manufacturer.
Diversified metals company, Multi-Alloys, has felt the effects of this and has put preventative measures in place in order to overcome it.
The company reports that in order to assure clients that Multi-Alloys is supplying reputable grades of stainless steel, the company has acquired its own x-ray alloy analyser which will be used for checking the outgoing and incoming material.
