AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. Forging of this steel should be carried out between 2200 and 1650 º F (1200 and 900 º C). This alloy finds many applications for the aerospace and oil and gas industries, along with uses the automotive, agricultural and defense industries AISI 1029 - AISI 1030 Carbon Steels All Metals & Forge GroupAISI 1029 AND 1030 carbon steels are effectively on the boundary of low and medium carbon steels, and as such may be classified as direct-hardening grades as opposed to carburizing grades. These grades are suitable for the manufacture of forged components that are subjected to low stresses, for automotive and general engineering.
AISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering. The tempering temperature for depends upon the strength level desired. For strength levels in the 260 280 ksi range temper at 232°C (450 F). For strength in the 125 Alloy Steel Archives All Metals & Forge GroupWeldability::pre-heat and post-weld stress relief are recommended for welding of this alloy. Welding should not be carried out in the hardened and tempered condition. To Send a Request for Quote, please Click Here, or call 1.973.276.5000 or 1.800.600.9290 or fax 1.973.276.5050.
