Product Description

AISI 4130 Alloy Steel 4x8 steel sheets aisi 4130 steel sheet

AISI 4130 steel stockholders and suppliers, delivering to the whole of the China. AISI 4130 is a chromium molybdenum alloy steel specification. It is supplied as round bar commonly in the hardened and tempered condition with a hardness of 18-22 HRc. With a lower carbon content range AISI 4130 provides better weldability, at the expense of through thickness strength, than that of other oil and gas steel grades such as AISI 4140. AISI 4130 alloy steel is readily machineable in the supply condition of 18-22 HRc.

Applications

AISI 4130 is widely used for a variety of applications in the oil and gas sector. Typical applications include components such as valve bodies, pumps and fittings.

Forging

Preheat carefully, then raise temperature to 950-1200°C for forging. Do not forge below 950°C.

Annealing

Heat the AISI 4130 slowly to 850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling.

Stress Relieving

When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to any hardening.

Hardening

AISI 4130 steel is usually supplied ready heat treated with a hardness of 18-22HRC. If further heat treatment is required annealed AISI 4130 should be heated slowly to 870-890°C and after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.

Tempering

Heat carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 400-570°C, soak at the temperature for 2 hours per 25mm of ruling section, then all to cool in the air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value.

Heat Treatment

Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult your heat treatment provider for full guidance on heat treatment of AISI 4130 alloy steel.

Certification

AISI 4130 alloy steel is available with a cast and analysis certificate or a BS EN 10204 3.1 mill certificate, please request when placing any orders.
