ASTM A242 steel work/steel structure/steel machining parts is a high-strength low-alloy structural steel for welded,riveted,or bolted construction intended primarily for use as structural members where savings in weight or added durability.The atmoSPHEric corrosion resistance of the steel in most environments is substantially better than that of carbon structural steels with or without copper addition.
Thickness range is between 1.5-80mm
Width range is between 1500-3800mm
Length range is between 1000mm-12000mm

The steel shall be made by one or more of the following processes: open-hearth, basic-oxygen, or electric-furnace.
We can arrange the LRS,ABS,BV,DNV,SGS,TUV etc,to do the third party inspection,the inspection items include UT test,PMI test,chemical composition test,mechanical property test,appearance inspection etc.
Katalor enterprises devote ourself to steel business both in international and domestic market. We have established long term relationship with China famous steel mills and traders.As a professional team,we can provide ASTM A242 steel work/ steel structure/ steel machining parts according to your drawings.Looking forward to cooperate with you!
