With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
SAE 4140 steel is widely used in many industrial fields for its strength and versatility, and therefore is important to know about if you are considering using it in your facility. Here is an outline of its key characteristics and most common applications.
4140 material is widely used in a lots of industrial fields. It is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. ASTM 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness.
4140 Steel Uses. AISI SAE 4140 alloy steel can be made into round steel bar, flat & square steel bar, steel plate, steel tube, and has many uses in the aerospace, oil and gas and automotive industries, typical uses are thin-walled pressure vessels, forged gears and shafts (Motor shafts, pump shafts, hydraulic shafts, etc.), spindles (lathe spindles, milling spindles, etc.), collars, clamps, high strength bolts, valve bonnet, screws, nuts, worms, collets, torsion bars and various carburized best 4140 steel uses

Steel alloy 4340 provides a good balance between strength and malleability. It is used in making gun parts, engine parts such as pistons, gears and bearings, and aircraft parts such as landing gear. With proper working and strengthening, items made from 4340 have excellent wear and durability qualities.
A popular example and perennial favorite in the U.S. is called SAE 4140 chrome-molybdenum or "chrome-moly" steel. In Europe, vanadium and nickel-steel alloys are preferred. Most standard barrels are made with alloy steels, as they offer an excellent balance of strength and cost.
Lets keep it simple. 4140 steel can be welded without problems as long as you follow some simple guidelines. We will not be discussing the metallurgical properties of 4140 or trying to explain what happens to its microstructure when it cools too rapidly. 4140 steel is alloyed with chromium and molybdenum, hence the term chromoly steel.
Some are better than others. What I can say is that 4140 is not second rate steel. It belongs in the group of steels that are suitable for axes hatchets and tomahawks. I make tomahawks and fokos for a living. When I started I experimented with a lot of different steels. I decided to use 4140 only because it impressed me , not for any other reason.
Adding too much carbon (up to 2.1%) makes the steel very very strong, but also much too brittle for a knife blade, and containing this much carbon also makes it impossible to form and shape the steel. Typically iron that has the maximum of carbon is called cast iron and is often used in fire stoves and kitchen pans.
Oil Hardening ( O-Grades) This is a general purpose oil hardening tool steel. It has good abrasion resistance and toughness for a wide range of applications. Typical applications of O-Grade tool steel include Arbors, Bushing, Chasers (Thread Cutting), Collets, Die Blanking, Cold Forming, Cold Trimming, Drill Bushing, Gages, Knurling Tools.
4140 is a nice, tough steel, too. If I had my rathers 5160 or 6150..1050-1060 is good, 1045 is pretty good to. We use damascus scraps and file steel(1095+carbon added %1.22) for the bit often times and the body mild steel.. The temper is really the important thing.
Having worked in a motor diecast department where we used a lot of H13, I can say that at the temperatures that you are running, most common steels (4140, 4340) will start to corode very quickly. We preheated the cores to 650-800 degrees in an oven, and had trouble anything that was plain steel under those conditions.

4140 High Tensile Steel 4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.
AISI 4140 is a low alloy steel. Low alloy steels rely on elements other than just iron and carbon to enhance their mechanical properties. In AISI 4140, additions of chromium, molybdenum, and manganese are used to increase the strength and hardenability of the steel.
Alloy steels are designated by AISI four-digit numbers and comprise different kinds of steels, each with a composition which exceeds the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels. AISI 4140 alloy steel is a chromium-, molybdenum-, and manganese-containing low alloy steel best 4140 steel uses
The AISI 4140 cold finished annealed chromium-molybdenun alloy steel can be heated using various methods to yield a wide range of properties, hence it is often used as stock for forging as it has self-scaling properties.
4130 alloy steel is one of the most important steel alloys. Basically, this alloy is better for heat treatment compared to others. High toughness of this alloy makes it different from others. Due to its toughness, it is used in aircraft for manufacturing leading gears and other parts.
Manufacturers use SAE 4140 for making average size automotive parts, such as axle shafts, propeller shafts and steering knuckles. SAE 4150 is used primarily for gears and other parts requiring hardness, strength and toughness.
Examples of applications for 4130, 4140 and 4145 include structural tubing, bicycle frames, gas bottles for transportation of pressurized gases, firearm parts, clutch and flywheel components, and roll cages. 4150 stands out as being one of the steels accepted for use in M16 rifle and M4 carbine barrels by the United States military.
4150 is commonly used in lawn mower blades and I have seen plenty of good knives out of them. 4140 is useable due to its alloy but its more along the lines of something I would use for hot tooling at the forge. 1045 again medium carbon about the same as 4140 but I would use the 4140 before that 1045. Both are awsome for hammers, decent for an axe.
Both use the same basic process,E7018 and a local preheat to 350-450f then a post weld draw down. In any process/material the best you can possibly do is produce a weld that is stronger than the base metal it is joined to,simple as that.If you have selected the wrong material,well back to the chicken salad rule again.
