Carbon steelEasily eroded, requiring careful maintenance, learned from Guangdong carbon steel foundry Cheng MaoCarbon steelFeatures are as follows:

1. The cutting edge can maintain sharpness for a long time

2. The price is more cost-effective

3. Easy to grind

4. Suitable for knocking with a lighter stick to get fire

5. High-quality steel suitable for knives

Stainless steel is generally more expensive and harder to grind

1. High corrosion resistance

2. Very durable

3. Requires less maintenance

4. It's also suitable for tapping with a lighter stick to get fire

5. It's also a better choice for survival knives

Guangdong carbon steel casting blade processing and coating:

In the whole process of tool manufacturing, the last link is generally the processing of the blade.

The processing and coating of the blade can improve the quality, durability and aesthetics of the blade.

The following are some of the most common Guangdong carbon steel casting blade processing.

1) Black oxide

Black oxide is a kind of blade coating, which can improve the corrosion resistance of the blade and also make the appearance of the blade more infectious.

It is not some simple black coating, generally simple black coating is of lower quality and is easy to scratch.

2) Sandblasting

Sandblasting is also a kind of coating, using a variety of materials such as sand or beads to carry out the sandblasting process on the surface of the blade.

This is done to better prevent the blade from reflecting light, but the surface of the blade is less smooth and easier to etch.

3) Titanium nitride

Titanium nitride coating, referred to asTiNi. It is one of the coatings that can be more high-end and has more process performance.

4) DLC coating

Everyone knows that it is one of the strongest coatings in the field of cutting tools.

It can make the blade quality higher, and the blade maintains long-term sharpness.

As everyone knows, this also means that their prices are generally much higher than other tool coatings.

5) Polishing treatment

It is a kind of blade processing for high-end tool applications.

The blade is polished during the entire manufacturing process, resulting in a highly reflective blade.

Polished blades are more resistant to corrosion than other blades.

However, this type of surface treatment is also very attractive in terms of visual effects.
