Leading Stainless Steel Sheet Suppliers in China

General properties：

• Ferritic, pure chromium, non-hardenable grade 430 has good formability and corrosion resistance in addition to practical mechanical qualities. Its ability to withstand nitric acid corrosion makes it helpful in some chemical applications; nonetheless, its main uses are in appliance parts and car trim.
• For use in automatic screw machines, grade 430F is a more machineable variation of this grade that is offered in bar form. Grade 434 is a molybdenum-containing grade that shares the same beneficial characteristics as Grade 430. The molybdenum that was added enhances corrosion resistance.
• ASTM A240/A240M specifies these 430 qualities for flat rolled goods (plate, sheet, and coil). Similar, though not often identical, qualities are listed in the specifications of other items, like bars and forgings. ASTM A582 specifies the Grade 430F characteristics for bars.

APPLICATIONS：

Typical applications for 430 grade include:

• Linings for dish washers
• Refrigerator cabinet panels
• Automotive trim
• Lashing Wire
• Element Supports
• Stove trim rings
• Fasteners
• Chimney Liners

Typical applications for 430F grade include:

• Repetition machined components

SPECIFICATIONS:

• UNS: ASTM/ASTE S43000
• DIN：1.4016

CORROSION RESISTANCE：

• Grade 430 material exhibits good resistance to a wide range of corrosive environments such as nitric acid and some organic acids. ​​​​​​Highest levels of corrosion resistance are achieved when highly polished or ground. Overall, its resistance to pitting and crevice corrosion is comparable to that of grade 304. Like all ferritic grades, 430 exhibits very high resistance to stress corrosion cracking.
• The non-free machining grade, 430F, exhibits significantly reduced resistance to pitting and crevice corrosion, as do the other high sulfur free machining grades.

HEAT RESISTANCE：

• Up to 870°C in intermittent service and 815°C in continuous service, grade 430 resists oxidation. This grade may require extended heating in the 400–600°C range before becoming brittle at room temperature. Annealing can be used to get rid of this effect.

HEAT TREATMENT：

• Solution Annealing – Heat to 815-845°C, hold for ½ hour per 25mm of thickness, slow furnace cool to 600°C and then quickly air cool. Slow cooling from 540-400°C will cause embrittlement.
• Sub-Critical anneal – Heat to 760-815°C and then air cool or water quench.
• This grade is not hardenable by thermal treatment.

WELDING：

• Pre-heat at 150-200°C if welding is necessary.
• Embrittlement in the weld metal and heat affected zone can be relieved by a post-weld anneal at 790-815°C
• Grain refinement will not occur.

MACHINING：

• Easier to machine than the standard austenitic grades such as 304.
• Still a tendency for galling and pick-up on the cutting tool.
• Bars that have been lightly drawn are easier to machine than those in the annealed condition.
• Grade 430F, the free machining version of 430, is very much easier to machine.

FABRICATION：

• Lower work hardening rate makes bending and forming somewhat easier than for grade 304
• Lower ductility restricts very severe operations.
• Severe bends should be made with the bend axis at right angles to the rolling direction.
• Severe cold heading of 430 wire is possible.

430 Grade Stainless Steel Sheets in a Variety of Finishes

Our stainless steel sheets (sometimes called steel sheets) are available in a range of beautiful finishes: brushed finish, 2B smooth finish or 8K mirror finish.

The finished side of each stainless steel sheet we supply is coated with a film. This film is easily peeled off after fabrication or installation and protects the surface of the material from wear and marks. The back side is unfinished.

430 Grade Stainless Steel Sheet is the most commonly used variety. It is easily weldable, formable, and has good corrosion resistance.

We can assist in providing stainless steel sheets in any required size.

To meet your specific requirements, our stainless steel sheets are available in three finishes and a variety of sizes. We can readily provide any custom size you may need with our free unlimited cutting service.

We are able to meet any size needs between 0.3 and 30 mm in thickness and between 50 x 50 mm and 2500 x 1250 mm in size. In addition, we provide free unlimited cutting with every order, using a state-of-the-art cutting machine to precisely meet your requirements.

Order Stainless Steel Sheets by Phone or Online.

There has never been an easier way to get stainless steel sheets. Simply refer to the simple and detailed instructions on our website. Alternatively, our sales staff will be happy to take your order or answer any questions when you call +86 13382898899 or email daxunhejin@gmail.com.

Important Safety Note:

The edges of the metal sheets we sell are not polished, ground or finished, so they may be sharp, just like the edges of any stainless steel sheet. We remind users to use, install and handle these devices with care.
