nameSaid:Damascus figured steel

Flat grinding, simple pickling state

Features: the practical sandwich pattern steel, the overall about 60 layers, the middle clip steel is VG10

Heat treatment: the steel clip HRC57 degree +-1, take into account sharp and toughness (steel clip has a good sharpness and hardness, vacuum deep cooling and heat treatment)

The pattern is spiral

The sale of steel material is flat grinding after Jian Yi pickling, everybody hands directly after forming / V

 Pay special attention to the problem:

1: there are plain grinding and simple pickling, but after forming / opening V, if necessary, it can be re washed once

2: the two sides of the pattern affixed to steel, because the relationship between the section may not be pure to the same thickness, the texture of the 2 sides will also be different;

3: the straight and pure steel, there will be a slight deformation of the stress in the heat treatment process, this is all steel properties, these all need friends back to DIY to their own satisfaction, ability and perseverance is stronger, have some of the necessary tools such as: grinding machine;

Process description1: do their own shape, after grinding more than 400# (preferably to 2000# above sub mirror effect)

2: use hydrochloric acid or battery water appropriate, put the knife embryo into the bubble
3: according to their own needs of the effect of pickling 30 seconds -10 minutes or so, it is recommended to spend less time (such as pickling for a minute or so, grinding and then pickling)
4: after washing, feel the effect satisfied, soak in water for 5 minutes or so, with alkaline substances such as soap / washing powder for neutralization and cleaning, and then cool dry on lubricating oil or edible oil for a maintenance on the line
 
 
Answer questions: 1: for pickling?
Answer: pickling, through the acid corrosion method, will be a little corrosion resistant components of Ma Steel Corrosion concave, so that the surface forming concave convex refraction light, so that the pattern is more obvious.
For pickling, this is a problem worth discussing, some think that cattle B friends is always in accordance with its own methods that do not try, good words, try out the problem to JJYY said something bad, or simply want to return / exchange shualai. Pickling concentration and surface Have the most direct relationship of grinding degree, surface oil must be clear, not satisfied with the results can be repeated several times, and less time to wash to the state if bump on the need to strengthen the global concentration can be a little more than 5 minutes, different components in different time, at the same time, the middle do not leak out prior to grinding steel and because the carbon content of steel is high, high acid sensitivity, direct soak for 5 minutes or more, is likely to fall directly to the steel corrosion; say that this is not really an artifact again, you know a piece of the same size 440C to more than 80, do not take the powder steel than others, a piece of steel more than 1000, 100 than you and I, then I say than others, I give up, there's really no meaning @

2: what is the clip steel Malaysia?

Answer: Steel Malaysian is a combination of different steel characteristics complement each other, the purpose is to strive for the balance between the performance of two or more steel products. This method is used in the process of making knives, the general use of materials is on both sides of the use of low hardness, toughness of steel; in the middle part of the blade using higher hardness steel. This can ensure that the blade has high hardness and high toughness and whole body.

3: polished will have no pattern of it?

Answer: after the blade pickling corrosion after soft polishing can get obvious effect (not printed). But with the grindstone or sandpaper to polish the pattern part is specially deliberately can rub the surface patterns, remove after re pickling can reproduce the pattern. Use the knife and normal (knife edge) is not breaking pattern, but there may be some small scraping scratches, hope you can understand, please correct deficiencies. Thank you More details please Baidu: Damascus knife

Sandwiched between the steel wire and a thick flat is not the first mock exam, because there will be differences between forging
