How to choose a flame retardant blanket to weld stainless steel

Flame retardant protective element in stainless steel welding.

Once again, we pretent to orient the use and selection of flame retardant blankets as a basic element of protection when we perform welding techniques, in this occasion when the metal to weld is stainless steel.

Stainless steel is well known by everyone, it is defined as an iron alloy that has iron as a fundamental element (FE) and in order for it to be stainless it must have a minimum of 10.5% of chrome (CR). Is a very hard and very heat resistant metal and also has a high resistance to oxidation, hence it stainless denomination. There are different types of stainless steels clasifying them according to the quantity of chrome they have.

In general terms, Stainless Steel = FE + Cr + C alloy

What should be taken into account to choose a welding blanket to protect ourselves from sparks and splashes dereved when we work with stainless steel?

1.We should know the fusion point from stainless steel.

Fusion point: between 1370 to 1400 degrees

2. Simply take into account that welding blankets meet the following technical features.

Offer resistance until 1500 degrees at least.
Good results to projection of big masses of melted metal
No burning nor melting
Effective as a barrier to block heat
Resistance to electric conduction. / thinking that during welding jobs it could occur any electric accident.

But, how do we know if the blanket we buy has this features?

For our part we ensire that the range of flame retardant product for protection TEXFIRE is created under strict quality controls and submitted to different proof tests meeting the requisites of regulations ISO 9185 ( splashes of big masses of melted metal) and ISO 11611 (welding and during connected techniques). TEXFIRE blankets are available in two sizes 100 x 150 and 150 x 200, though, in addition, to be used no matter the distance, nor its position or the used face.
TEXFIRE also puts into your disposition flame retardant fabrics from 150 linear meters wide, suitable by its width to protect larger areas.
