Our Products
We are leaders in the market for providing best range of Alloy Steel and Stainless Steel
AISI 4130 steel stockholders and suppliers, delivering to the whole of the UK.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.
| Form of Supply | Supreme Steel are AISI 4130 steel stockholders and suppliers of round bar. Diameters can be supplied as full bar lengths or cut blanks. AISI 4130 ground steel bar can be supplied, providing a high tensile alloy steel precision ground bar to tight tolerances. Contact our experienced sales team who will assist you with your AISI 4130 steel enquiry. |
| 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 950-1200C for forging. Do not forge below 950C. |
| Annealing | Heat the AISI 4130 slowly to 850C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480C 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 870-890C 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 400-570C, soak at the temperature for 2 hours per 25mm of ruling section, then all to cool in the air. Tempering between 250-375C is not advised as tempering within this range will seriously reduce the impact value.

420 stainless steel stockholders and suppliers, delivering to the whole of the Middle east. Available in different variations of carbon content 420 stainless is suitable for heat treatment. 420 stainless has a 13% chromium content which gives the specification a level of corrosion resistance properties.
| Form of Supply | Diameters can be sawn to your required lengths as one offs or multiple cut pieces. 420 stainless steel plate and sheet are available to European steel grades 1.2083 and 1.4034, which can be supplied as full plates and sheets or can be cut to your requirements.
|
| Applications | 420 stainless is widely used in the medical and cutlery industries. It is suitable for applications such as instruments, knives, hand tools, pump shafts and plastic moulds. 420 is not recommended for use in temperatures above the relevant tempering temperature, because of the reduction in mechanical properties. |
| Hardening | 420 is suitable for heat treatment up to 52 HRc or higher depending on the carbon content and size of the component. European grade 1.2083 is a high carbon type 420 stainless and is ideally suited for application where highest achievable hardness is required. |
| Certification | 420 stainless steel grade is available with BS EN 10204 3.1 mill certificate or cast and analysis certification. Please request any material certificate requirements when placing your order. |
| Quality Assured Supply | Stainless Steel 420 specification is supplied in accordance with our ISO 9001 : 2008 registration. |
