The correlation between properties and parameters-S45C (JIS)-SAE1045(Aisi)-SM45 of No. 45 steel(45 steel) was studied:
No. 45 steel is a carbon structural steel with 0.45% carboncontent. It is characterized by low price, good cutting performance, high hardness after quenching, good strength, toughness and wear resistance after quenching and temperingtreatment, is widely used in manufacturing structural partsand low-grade plastic mold. “45 steel” is a popular name, thesymbol is generally recorded as”45 #”. In fact GB standardsteel number is”45″, it is not a sequential number, read as”45steel” is not very accurate. Ingredient code 45 steels of similar designation are S45C (JIS) and 1045(Aisi) . In addition, ourcountry metallurgical technology standard has SM45 brandnumber to express the plastic mold use specially. Comparedwith 45 steel, SM45 has lower phosphorus and sulfur contentand better steel purity.

Recommended process specification for heat treatment andhardness: quenching temperature 820 – 860″ C, water-oroil-cooled, hardness 250 HRC. Recommended tempering pro-cess specifcation: tempering temperature is 500 – 560″ C, aircooling, hardness is 25 – 33HRC. Tempering in this temperature range is the tempering treatment, Quenching and tempering make the strength, plasticity and toughness of 45 steelget a good balance, the comprehensive performance is good,can adapt to the alternating load environment. After quench-ing and tempering, the surface hardness of 45 steel is low anddoes not wear well. So commonly used quenching and tempering + surface quenching to improve the surface hardnessof parts.

FAQ

What is the difference between forging and casting?
Forging: It is the process of transforming a solid from 1 shape to another. Casting: It is the process of transforming a shapeless liquid metal into a solid with a shape. The so-called casting is the process of casting molten metal into a model to obtain a casting. The casting profession focuses on the metal melting process and the control of processes during the casting process. Forging is a plastic forming process in the solid state, which can be divided into hot processing and cold processing. Forgings include extrusion, drawing, roughening, punching, and so on. Casting is a solid liquid solid process, while forging is a solid to solid process where a solid can change its shape into another shape at high temperatures. There are still differences in the shape process and process of the two.

How to choose high-quality forgings?
In the quality inspection of forgings, there are mainly external observation methods and internal inspection methods. The appearance method, as the name suggests, is to observe the appearance of the product, such as the shape, geometric dimensions, surface condition, etc. of the forging, in order to understand whether it meets the standards and whether there are external defects. Specifically, it is to check whether the external dimensions of the forging meet the specifications and whether there are defects on the surface, such as cracks, wrinkles, bubbles, indentations, pits, impurities, scratches, etc. on the surface of the forging. Internal testing mainly involves analyzing the chemical composition, macroscopic and microscopic structures, and mechanical properties of forgings. This inspection process requires the use of specialized instruments for high magnification inspection, with the aim of checking for any phenomena such as fractures and shrinkage within the forging, as well as defects such as dendrites and white spots, disordered flow lines, and throughflow. It also includes the tensile strength, ductility, hardness, plasticity, and heat resistance temperature of the forging.
-
What are the characteristics of the forging process for blank forgings?
The forging process of circular forgings mainly consists of the following processes: pier roughening, elongation, punching, and expanding. The difference between free forging and ring rolling processes is mainly in the process of expanding holes. In the production of ring forgings, free forging is usually used to expand the hole with a horse screw, while ring rolling is mainly used to expand the hole with rolling.

What are the signs of a worn or failing axle, and how can I troubleshoot axle issues?
Identifying the signs of a worn or failing axle is important for maintaining the safety and functionality of your vehicle. Here are some common signs to look out for and troubleshooting steps you can take to diagnose potential axle issues:
- Unusual Noises:
- Vibrations:
- Uneven Tire Wear:
- Difficulty Steering:
- Visible Damage or Leaks:
- Professional Inspection:
If you hear clunking, clicking, or grinding noises coming from the area around the wheels, it could indicate a problem with the axle. These noises may occur during acceleration, deceleration, or when turning. Troubleshoot by listening carefully to the location and timing of the noises to help pinpoint the affected axle.
A worn or failing axle can cause vibrations that can be felt through the steering wheel, floorboard, or seat. These vibrations may occur at certain speeds or during specific driving conditions. If you experience unusual vibrations, it’s important to investigate the cause, as it could be related to axle problems.
Inspect your tires for uneven wear patterns. Excessive wear on the inner or outer edges of the tires can be an indication of axle issues. Misaligned or damaged axles can cause the tires to tilt, leading to uneven tire wear. Regularly check your tires for signs of wear and take note of any abnormalities.
A worn or damaged axle can affect steering performance. If you experience difficulty in steering, such as stiffness, looseness, or a feeling of the vehicle pulling to one side, it may be due to axle problems. Pay attention to any changes in steering responsiveness and address them promptly.
Inspect the axles visually for any signs of damage or leaks. Look for cracks, bends, or visible fluid leaks around the axle boots or seals. Damaged or leaking axles can lead to lubrication loss and accelerated wear. If you notice any visible issues, it’s important to have them inspected and repaired by a qualified mechanic.
If you suspect axle issues but are unsure about the exact cause, it’s advisable to seek a professional inspection. A qualified mechanic can perform a thorough examination of the axles, suspension components, and related systems. They have the expertise and tools to diagnose axle problems accurately and recommend the appropriate repairs.
It’s important to note that troubleshooting axle issues can sometimes be challenging, as symptoms may overlap with other mechanical problems. If you’re uncertain about diagnosing or repairing axle issues on your own, it’s recommended to consult a professional mechanic. They can provide a proper diagnosis, ensure the correct repairs are performed, and help maintain the safety and performance of your vehicle.
