Suitable for electric discharge, grinding processing, suitable for high mirror high precision injection mold kernel mold cavity, heat treatment has a high hardness and toughness, can also do stamping mold accessories, templates, etc., on the surface of the contact product requirements jig molds, etc.; applicable to the general high-temperature rust corrosion resistance scene.

Can make dining knives, and outdoor knives.

 اختيار السكاكين

In the purchase of kitchen knives, it is necessary to consider their needs in advance, such as what ingredients are often dealt with, preference for Western or Chinese, etc. It is best to go to a shopping mall or other places to select knives and try them in your hand to see if they are smooth, the right size, and weight. If you are on a budget, try to choose knives from trusted brands with good quality.

Material, stainless steel knives are easy to operate, easy to polish, long service life, not easy to chipping wear, and have more corrosion-resistant rust; traditional Chinese kitchen knife more than the use of carbon steel, it is easier than stainless steel knives to sharpen, but not easy to maintain, prone to rust; ceramic knives are more antimicrobial, hardness is higher, sharper, cut food will not be skewered, but inadvertently dropped, or cutting harder food or cutting boards are prone to chipping.

In the use of kitchen knives, it is best not to chop hard ingredients; in addition, the wooden cutting board must “foster” the knife, because the knife can be cut into the wood, and there will not be a “hard to hard” situation; in the use of the first before cleaning, more to wash, dry after use, so as not to rust.

ماذا عن الفولاذ المقاوم للصدأ 40Cr13؟

يعتبر الفولاذ 40Cr13 جيدًا جدًا لصنع سكاكين المطبخ.

40Cr13 (old grade 4Cr13) is martensitic stainless steel, the highest carbon content in the Cr13 series, with the steel to do kitchen knives are both sharp and not embroidered, and medical scalpels are processed with this material.

40Cr is China’s GB standard steel number, 40Cr steel is one of the most widely used steel in the machinery manufacturing industry. After tempering treatment has good comprehensive mechanical properties, good low-temperature impact toughness, and low-notch sensitivity. The steel has good hardenability.

4Cr13 is more suitable for cutting tools, 4Cr13 is more quenched than 3Cr13 hardness is a little higher, good corrosion resistance, use: used as cutting tools, nozzles, valve seats, and so on. Hardness : annealed, ≤ 201HB; quenched and tempered, ≥ 50HV.
