Heat Treating 4130 Sheet Metal

Test reports are required there s a minimum 15 00 charge per order.

Heat treating 4130 sheet metal. Heat treatment aisi 4130 steel is heated at 871 c 1600 f and then quenched in oil. Forging of aisi 4130 steel can be performed at 954 to 1204 c 1750 to 2200 f. There are four main ways to heat treat steel alloy. Tensile strength 75 000 85 000 psi.

Heat to 900º c 1650 º f. Austenitize at 870º c 1600 º f and quench in oil. Annealing normalising hardening and tempering. Actually when forgings are normalized before say carburizing or hardening and tempering the upper range of normalizing temperatures is used.

Sheared to sheet and strip sizes listed below. The reason they wanna talk is there is a large dip in the impact properties through this temper range. Most heat treaters will want to have a talk with you if you re asking for a temper between 500 and 900f with 41xx. Water quenching will achieve a higher as quenched hardness than oil quenching.

Less 10 discount on 6 sheets 18 x 36 or 3 sheets of 18 x 72 per part number. With the torch keep the metal in the hottest part of the flame to reduce the oxygen reaching the metal. Tempering reheating after quenching will achieve the desired hardness range. At 45rc for 4130 it s about a 650f draw.

The yield strength and ductility are better at higher hardnesses than with 1050. Heat treatment the reason for heat treatment is to prepare the alloy for machining and to enhance 4130 steel properties. The heat treating process is much more forgiving with 4130 than with 1050 carbon steel. For high carbon and alloy steels annealing.

Hold the metal with a pair of metal tongs. For 4130 steel the recommended heat treatment consists of heating to austenitizing temperature typically 1600 f 870 c followed by water quenching. For common carbon steels the cooling can be done in dry ashes lime powder or vermiculite. Cool 4130 steel in air.

This steel is usually heat treated at temperatures ranging from 899 to 927 c 1650 to 1700 f. In the usa 4130 is currently easier to purchase in small amounts than 1050. Ferrous metals are annealed by heating to just above the a3 point a point above non magnetic that varies with the carbon content and then cooling slowly. Annealing is the softening of metal by heat treatment.

When normalizing is the final heat treatment the lower temperature range is used. Welding filler rod is available in 4130 but not in 1050.
