Ninthore Overseas Is One Of The Leading Manufacturer And Exporter Of High Quality AISI 4130 Beam, Angle, Channel, Chain, which has excellent quality that the possibility of designing thinner walls can save cost. Often referred to as an excellent grade due to the molybdenum content, AISI 4130 Angle has the ability to withstand high temperatures and maintain strength under volatile conditions. Commonly used as a replacement in critical components of larger constructions where SS 316L or SS 317L has failed by pitting or chloride stress corrosion cracking, AISI 4130 C-Channel withstands the same corrosive environments.

AISI 4130 Beam

In new construction, AISI 4130 Chain has been found in many cases to be a technically adequate and more cost efficient substitute for other nickel based alloys and titanium, where the allowable design values may be about 50 % higher than those for standard austenitic steels. AISI 4130 I-Beam is often considered a “high end” austenitic stainless, which is further readily fabricated and welded.

AISI 4130 H-Beam offers chloride resistance superior to that of other alloys and is especially suited for high chloride environments such as brackish water or seawater. AISI 4130 T-Beam is an austenitic stainless steel, compatible with the common austenitic stainless steels, designed with high levels of chromium, molybdenum, and nitrogen for maximum resistance to pitting and crevice corrosion. Offered to client’s at the most reasonable rate possible, the offered range of AISI 4130 Steel Angle is known to have a high preference in the market.
