S45C Hard Chrome Plated Precision Steel Bar Cold Drawn Chrome Bar

Chrome plated steel bars are chromium-plated steel products that can be supplied as piston rods in standard hydraulic and pneumatic applications. The chrome plated steel bar is normally used in conditions of high stress, friction and harsh climactic environments, so the quality of the base metal and subsequent surface treatment are of paramount importance. Wear resistance, corrosion resistance, surface smoothness, high yield strength and uniform quality are essential properties of hard chrome bar.

Hard Chrome bars are generally produced from steel bars combining high strength with excellent machinability and weldability. Common applications are found in agricultural machinery, production equipment, cranes, garbage compactors, lifters etc.

Steel Grade according to different standards

Induction hardening: it is a form of heat treatment in which a metal part is heated by induction heating and then quenched. The quenched metal undergoes a martensitic transformation, increasing the hardness and brittleness of the part. Induction hardening is used to selectively harden areas of a part or assembly without affecting the properties of the part as a whole. The hardening depth is 1.5-5mm; medium/low-frequency quenching may lead to excessive depth and negative effect on strength; high-frequency quenching generally result in a shallow depth, and may ensure the balance of hardness and strength.

Quenching and high-temperature tempering: Generally, the heat treatment method combined of quenching and high-temperature tempering is called thermal refining, which is widely applied to various important structural parts, especially the connecting rods, bolts, gears and shafts working under alternating load. The tempered sorbite has better mechanical property than normalized sorbite of the same hardness. Its hardness depends on tempering temperature and relates to stability of tempering and sectional dimension of workpiece, and is generally HB200-350.

Induction hardened with Q&T: After induction hardening with Q&T, the piston rods could not only obtain greater mechanical properties, but also achieve a greater resistance to damage from external impact.

Anhui Elite Industrial Co.,Ltd

is a mechanical parts welding manufacturer that integrates design, manufacturing, assembly, testing, and exporting, proudly providing a comprehensive solution for mechanical parts. Our company is based on OEM, but adhering to the concept of "quality priority, intellectual first", while pursuing quality our company has gradually paid attention to design and manufacturing processes, and expects to accomplish the goal of over-OEM to ODM in the future.

Elite's production base is located in the beautiful City Kunshan, with a factory area of 22,000 square meters and a construction area of 14,000 square meters. Founded in 2011, our company has more than 100 outstanding employees, more than 20 office technicians, with a high-level welding team consisting of several international welders (ISO 9606-1 International Welders Certificate) and senior welders, also with a group of skilled machining operators and a skilled assembly team.

We passed the ISO9001 quality assurance system in 2011 and established own quality control team. We continuously receive and learn the customer's requirements for product quality, and conscientiously implements the quality-first service-best management concept, therefore we accumulated a good reputation in the industry field and received customer’s recognition simultaneously.

Our company has the CNC flame cutting machine, plasma cutting machine, laser cutting machine, CNC boring and milling machine, 6meter CNC gantry machining center, 8meter gantry boring and milling machine, 4meter CNC guide grinding machine, TRUMPF laser cutting machine, 4 to 8 meters Bending machines and various common welding machines.

We have High-precision testing equipment such as Hexagon gantry three-coordinate detector(DEA ALPHA) , Leica laser tracker and articulated arm measuring instruments. Besides using the efficient equipment to solve problems, our technical team is constantly researching new production processes to meet the new requirements in the market, and also invest more advanced machining and welding equipment.

At present, our main products focus on welding parts, machined parts, industrial pressure platens, guide rods /column/pillar, press roller, calender roller and other machine body with accessories, for the large welded structural parts can be made to a single weight of 15 tons, the thickness of the heating platen and insulation board can be made a tolerance of ±0.1mm from 20mm to 200mm, the rod column can achieve Max. Φ300mm with length in 6 meter, surface with chromed coating by thickness up to 0.07mm.

We can also pre-assemble equipment components according to customer requirements, such as assembly of some fixtures and welding line bases. Our customers spread both domestic and foreign markets, we’re working with some of FORTUNE GLOBAL 500 and eventually becomes a long-term stable partner.

We attach great importance to the talent training strategy, regularly conducts knowledge and operation standards training for new employees, and enables competent employees to further study. Currently we cultivated a group of assistant engineers, intermediate welders, intermediate molders, electrical technicians, welders, and testing personnel, with these people we're confident to the future.

In the past years, we have been working hard to grow and thrive.

Through continuous learning and accumulation, we brought high-quality products and services to customers, provided employees with a reliable platform and place, got opportunities and challenges.

We hope that in the next chapter, we will continue to maintain our customers and be success.
