Q:I have my grandpa's navy knife from ww2, a mk2 combat knife i think, and i was wondering what type of steel it is made of. I'm guessing it's a high carbon steel, i'd just like to know exactly what grade.

1095 Steel - Easy to sharpen, plain carbon steel used in knife making. Proven to be one of the most popular steels used in KA-BAR knives. Right from the OEM site. Worked for a company that started in 1859 as a safe manufacturer. The steel recipes have not changed much from WWII (when Elliot Ness was running the company) to now. Doubt the KA-BAR recipes has changed either.

Q:What are the key factors affecting the strength of a steel coil?

The key factors affecting the strength of a steel coil include the grade and composition of the steel used, the manufacturing process and techniques employed, as well as the heat treatment and cooling methods implemented. Other factors such as the thickness and width of the coil, as well as any mechanical or surface treatments applied, can also influence its strength.

Q:What are the common welding techniques used for steel coils?

Steel coils can be welded using different techniques, such as shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and flux-cored arc welding (FCAW). SMAW, also known as stick welding, involves creating an arc between the welding electrode and the base material using an electric current. The electrode is coated with flux, which shields the weld from atmospheric contamination. This versatile technique can be used for both thick and thin steel coils. GMAW, commonly known as MIG welding, is an automated process that uses a continuous wire electrode and shielding gas. The electrode is fed through a welding gun, and an electric current creates an arc with the base material. This fast and efficient technique is suitable for high-volume production of steel coils. FCAW is a variation of GMAW that uses a tubular electrode filled with flux instead of a solid wire. The flux provides shielding gas and additional fluxing agents to protect the weld from impurities. FCAW is often preferred for welding thicker steel coils due to its better penetration and higher deposition rates. In addition to these techniques, laser welding and electron beam welding can be used for specific applications in steel coil manufacturing. These methods offer precise and high-quality welds but are typically more expensive and require specialized equipment. Ultimately, the choice of welding technique depends on factors such as material thickness, production volume, and specific product requirements.

Q:How are steel coils used in the production of electrical wiring?

Steel coils are used in the production of electrical wiring as a core material for the conductors. The steel coils are typically shaped into a cylindrical form and coated with an insulating material. This helps in providing structural support to the wiring and also enhances its conductivity and durability.

Q:Can you use regular welding rods when welding stainless steel?Thank you.

Yes you can use regular welding rods for stainless steel. But you will not have the properties of the stainless. The weld joint will have a different color than the stainless if you grind/grain/finish the weld. It could also rust. The joint could be weaker. It is best to use a rod that comes as close to the base metal stainless as possible. (30 years welding - certified)

Q:I am in the market for a good hunting knife under $100. I am primarily looking for a knife that will keep it's edge. What type of steel should I be looking for?

Get a Kershaw hunting knife. Kershaw uses only good quality knife steel and they have plenty of hunting knives under $100.

Q:If you keep it dry and clean, what steel will last the longest over the years with continued use and sharpening?

you eventually will wear the blade out. i have seen old guys pocketknives that they used for whittlin and the blades have deep curves in them like khukris from wear. i reccommend, 440 stainless, or something with a rockwell hardness rating above 45.

Q:What are the different types of steel surface finishes for coils?

There are several types of steel surface finishes for coils, including hot rolled, cold rolled, galvanized, and coated finishes. Each finish offers unique properties and characteristics, such as improved strength, corrosion resistance, or aesthetic appeal. The choice of finish depends on the specific application and desired outcome for the steel coils.

Q:What would be a better knife one with damascus steel or one without? Why is damascus steel so special other than the look? And why do some people say high carbon steel is better than regular? mainly though I want to know about the damascus. Thanks, max points to best answer.

It all depends on the steel. There are as many types of Damascus as you want to imagine. The old Damascus swords brought back by the Crusaders were far superior to the blades made in Europe at that time, but they probably wouldn't match up to modern steel in performance. Alas, it has been lost to history as to how they were made. Back to modern times. Damascus can be homogeneous steel with the pattern hammered in (hammered steel) or layered (pattern welded) or any number of variations. I make many blades out of crane cable, the pattern is nice and the strength is superior to all others. Layered damascus, done correctly, can have what is called the Damascus cutting effect (DCE). These knives are rare and expensive. The best layered blades are made of high carbon steels of various alloy content. I just recently finished a low count blade made of L-6 and a file (W-1), these offer exceptional edge holding. Factory blades are often not worth buying unless you like pretty knives. I personally make mine to be used. I could write a book on the subject, but others already have. In the end a knife is as only as good as the heat treating, good steel with a bad heat treat will not perform as well as lower quality steel done properly.

Q:How are steel coils processed and shaped into various products?

Steel coils are processed and shaped into various products through a series of manufacturing processes. First, the steel coil is uncoiled and cleaned to remove any impurities. Then, it goes through a process called leveling, where the coil is flattened and straightened. Next, the steel is cut into the desired length or shape, using techniques like shearing or slitting. After that, it may undergo additional processes such as forming, bending, or rolling to give it the desired shape. Finally, the steel is often treated with coatings or finishes to enhance its durability and appearance.
