Company Introduction and Product Overview
Hemaokang Steel (Shandong) Co., Ltd. is a professional manufacturer and exporter of carbon steel products, serving industrial customers across multiple continents. Our AISI 1045 carbon steel rod is produced in diameters ranging from 10 mm to 200 mm using cold drawing and precision grinding technologies, delivering a clean and uniform round bar for demanding machine applications. The product is designed for shafts, pins, rollers, guide rods, and many other components where medium carbon steel strength and accurate dimensions are required.
Cold drawing improves the surface quality and tensile properties of the steel, while precision grinding gives it a fine finish and close tolerance. This combination makes the rod especially suitable for CNC turning, milling, drilling, and grinding processes, because the uniform diameter reduces the need for heavy stock removal. As a supplier, we focus on stable quality, flexible cutting services, and responsive communication for both standard and custom orders.
Key Features
- Wide diameter range: 10 mm to 200 mm, for light-duty precision pins as well as heavy industrial shafts.
- Cold drawn process: Improves tensile strength, yield strength, and surface finish compared with hot rolled products.
- Precision ground surface: Provides a smooth, bright surface suitable for close-tolerance assemblies.
- Good machinability: AISI 1045 offers stable machining behavior in production environments.
- Good roundness and straightness: Controlled processing helps maintain straight bars for long shaft applications.
- Customizable lengths: Available in fixed lengths, random lengths, or cut-to-size pieces according to drawing.
- Suitable for hardening: 1045 can be induction hardened or flame hardened for surface wear resistance.
- Consistent quality: Production is carried out under ISO9001 quality management procedures.

Material and Performance Details
AISI 1045 is a medium carbon steel with a nominal carbon content of about 0.45%. It is selected when higher strength and hardness are needed than low carbon steels can provide, while still maintaining adequate ductility for general fabrication. The cold drawn and precision ground condition improves the bar's surface finish and dimensional accuracy, which helps customers reduce preliminary machining operations and production costs.
The bar can also be supplied in different surface conditions depending on final use. For example, customers may request turned and polished bars, peeled bars, or centerless ground bars. Cutting, chamfering, and straightening are available as processing services. These optional treatments can be arranged based on customer drawings or application requirements.
Typical Applications
- Transmission shafts and motor shafts
- Linear motion shafts and guide rods
- Precision pins, dowel pins, and locating pins
- Rollers, pulleys, and bearing housings
- Hydraulic cylinder components and piston rods
- General engineering parts for machining workshops
- Agricultural machinery, construction machinery, and automotive components
Quality Assurance and Production Control
Quality control is a key part of our manufacturing and supply process. Our team monitors material selection, drawing, grinding, straightening, and final inspection to ensure that each rod meets the customer's specifications. We maintain an ISO9001 quality management system, which applies to our internal production and export operations. Material test certificates, dimensional inspection reports, and other requested documents can be provided to support qualified procurement.
Because our factory team in Liaocheng, Shandong is supported by experienced operational staff, we are able to handle regular stock replacement and custom processing requirements. Every order is checked before packing to reduce the risk of dimensional or surface issues. This focus on process control gives customers confidence in product consistency.
Export and Shipping
Hemaokang Steel (Shandong) Co., Ltd. ships goods through Qingdao port, one of the main export ports in China. Our export team serves markets in North America, South America, Eastern Europe, Western Europe, Southeast Asia, Africa, Oceania, the Middle East, and Central America. With an annual export value in the range of US$50 million to US$100 million and a team of 51 to 100 people, we have the capacity to support large volume orders and time-sensitive deliveries.
We offer practical packaging solutions such as bundled steel rods, protective wrapping, and container loading according to order size. For customers who need just-in-time delivery, we can coordinate production and shipping schedules to match project timelines. Quotations can be prepared on request for specific diameters, lengths, and quantities.
Frequently Asked Questions
What is AISI 1045 carbon steel used for?
It is commonly used for shafts, pins, rollers, studs, and general machine parts that require good strength and wear resistance. It is also used when a medium carbon steel with good machinability is needed.
Can you supply rods in diameters other than 10 mm to 200 mm?
Our standard range covers 10 mm to 200 mm. If you require a diameter outside this range, please contact us to confirm availability or alternative processing.
What length options are available?
We can supply fixed lengths, random lengths, or cut-to-size pieces. The preferred length should be specified in your inquiry so that we can provide accurate pricing and packing details.
What is the difference between cold drawn and hot rolled round bars?
Cold drawn bars have better surface finish, tighter tolerances, and higher strength due to work hardening. Hot rolled bars usually have a rougher surface and wider tolerances. For precision applications, cold drawn and precision ground bars are preferred.
Can the bar be heat treated?
Yes. AISI 1045 can be normalized, quenched and tempered, or induction hardened depending on the application. Heat treatment can be arranged according to customer technical requirements.
Do you provide material certificates?
Yes. Material test certificates and inspection reports can be provided upon request to verify the grade and condition of the steel.
How are the rods packed and shipped?
Rods are bundled, protected with anti-corrosion measures or wrapping, and loaded into containers or flat racks. Shipping is arranged mainly from Qingdao port.
Can I request a sample before placing a bulk order?
Sample orders are welcome. Please send your required diameter, length, and quantity, and our sales team will reply with availability and delivery time.
