Sachiya Steel International is One Of The Leading Manufacturer And Exporter Of High Quality Alloy 20 Nuts And Bolts, which can be formed by hot – working or cold – work using traditional methods. Depending on who you talk to this alloy may be referred to as Alloy 20 Hex Head Bolts or as a nickel alloy, where either way it is still great for corrosion resistance. Applications of Alloy 20 Hex Head Nuts are limited to a maximum temperature of 1000 Degree F per ASME. Alloy 20 Square Bolts is a heat resisting steel with high resistance to oxidization scaling and has high strength at elevated temperatures.

Alloy 20 Nuts

               Alloy 20 Nuts

Alloy 20 Square Nuts may be welded victimization all of the common attachment processes. Alloy 20 Eye Bolts is combined with higher creep properties at temperature and unsullied is incredibly powerful and ductile. Alloy 20 Eye Nuts has smart resistance to oxidization and will be employed in continuous service up to 1140 Degree C provided reducing Sulphur gases don’t seem to be gift.

Our ability to provide Alloy 20 T-Bolts on a project basis is one of our strongest capabilities and is  unmatched in our industry. We offer tailor made Alloy 20 T-Nuts with suitable wedge options, where it can even be a substitute of Austenitic grade of marine surrounding. The high metal and nickel contents of Alloy 20 Hex Bolts offer comparable corrosion resistance, superior resistance to oxidization.
