4140 Steel Uses

AISI SAE 4140 alloy steel can be made into round steel bar, flat & square steel bar, steel plate, steel tube, and has many uses in the aerospace, oil and gas and automotive industries, typical uses are thin-walled pressure vessels, forged gears and shafts (Motor shafts, pump shafts, hydraulic shafts, etc.), spindles (lathe spindles, milling spindles, etc.), collars, clamps, high strength bolts, valve bonnet, screws, nuts, worms, collets, torsion bars and various carburized parts.
AISI 4140
AISI 4140 also known as EN19 comes treated in the annealed as rolled or even T condition. We can offer AISI 4140 in bar form from stock, rolled and bright drawn. It is renown for its wear resistance and where high strength properties is required. Suitable for gears, shafts, spindles, etc. Frequently used within the gas and oil industry. For improved weldability consider using 4130.

The 41xx family of steel include chromium and molybdenum and are often referred to as chromoly steel or chrome-moly. Chromoly steels have an excellent strength to weight ratio but do not contain sufficient quantities to provide the levels of corrosion resistance found in stainless steels. These steel are often used in aircraft parts also frequently used within the gas and oil industry.

4. Packaging

  In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging：



According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.

Packing standard: according to the following national standard requirements (the parts beyond the requirements will be specified separately)

GB／T191 packaging-pictorial marking for handling of goods

GB／T4857 (all parts) basic test for transport packages

GB／T4879 rustproof packaging
