FAQ

1.What's your MOQ?
25MT, it is for one container.
2.Do you have QC teams?
 Yeah, sure, our QC team is very important, they will keep the quality control for our products.
3. What's your normal delivery time?
Our delivery time about 10-20days for standard sizes, if you have other requirements like hardness  and width ,it is about 20-40days. But don't worry ,we also try our best for the delivery time ,because time longer and our cost is higher.
4.Are the products tested before shipping?
Yes, all of our PPGI and GI was qualified before shipping. We test every batch every day.

Q:is 440 stainless steel good for throwing knives?
For throwing knives, 440 isn’t necessarily a bad choice. Does it list whether it is 440c or 440b? That matters somewhat. The advantages of 440 Stainless is that it’s relatively hard (for a stainless), it resists rust significantly, and it’s not so hard that it would shatter or break. On the down side 440 is notorious for not taking or holding an edge, but for a throwing knife, that’s probably not much of an issue. If you’re looking for something to train with, you’re fine here. It’s plenty of steel enough to stick in wood or other targets. Odds are it won't bend if you slam it into some wood. If it lands on concrete, eh, it's going to scratch and all that jazz, and it might hurt the tip if it hits first, but as has been said, you can use a file or grinder to get the tip back.
Q:grain growth in steel?
There is such a thing as critical strain which will lead to extraordinary grain growth on annealing;but not without annealing.It would be to do with the density of grain growing sources and clearly the density of these nuclei woul increase with increasing severity of strain so I just of a guess that that those parts of a pressing with least strain might grow most.But I must tell you that in the case of Aluminium alloy extrusions severe and expensive coarse grain occurs near the surface and particularly toward the back end of the bar;so this would be where most severe deformation takes place.However in a pressed steel part you have all possible circumstances,some of which on ironed walls will resemble extrusion,others would be bending strains,tensile and compressive .I have to cop out of this now because as old wasname above,said it depends.But bear in mind that it is unlikely that the material you mention would be hot pressed,further .coarse grain might only be a surface problem and is likely to be cured by normalising so that new ferrite grows from austenite.A similar solution does't exisat for Al alloy extrusions,it has to be machined off.In a cold steel pressig you would only expect to see a cold worked sructure because the recrystallisation temperature of pressable steel would not be less than,say 550 degrees C .
Q:Is stainless steel magnetic?
Some stainless steel are magnetic and some aren't. The real high grade stainless steels aren't magnetic.Stainless is just regular steel with varying degrees of nickel and chromium alloys mixed in the batch. The more nickel and chromium the less likely to be magnetic. A lot of stainless exhaust pipes and barbecue grills claim to be stainless, and yet they still rust and tend to be magnetic. They must use the bare minimum of nickel and chromium in the melted batch just to claim the title of stainless steel. Nickel and chromium are quite expensive and they are what gives the steel the anti-corrosion and extreme hardness characteristics along with loss of magnetism of the steel. If you have stainless steel that is magnetic , it is a good sign it is stainless steel that barely meets the criteria of true stainless steel.
Q:How is steel coloured?
Steel can be plated(Chrome),Blackened(Black Oxide),Powder coated(color of your choose).All of this is done to prevent rust.All of these aforementioned processes can be worn off through being used.I suggest polished Stainless steel.
Q:stainless steel cookware sticking?
Welcome to the life of stainless steel cookware. Make sure you have plenty of steel wool handy. It took my wife and I some getting used to, but we now love our set.
Q:Why is it called Stainless Steel?
It is called stainless because it is much more highly resistant to rust and corrosion. It is stainless in camparison to other steels, such as carbon steel.
Q:what is cast steel? what is the contain? it is diffrent from cast iron?
Casting is a process of forming a part just like forging or rolling are also processes of forming steel. Cast steel can be any grade of steel poured into a sand mold to form a part like a water pump housing in your car. To be classified as steel, the mixture usually contains less than 2% carbon. Cast iron is a mixture that generally contains more than 2% carbon. It also can be poured into a sand mold. There are many grades of iron. Many metals can be cast into shapes like the air intake plenum on your car is probably cast aluminum. Bronze statues are made by pouring molten bronze into a mold. The process used to create a part has an effect of that part's mechanical properties. A casting is weaker than a forging but certain parts cannot be formed by forging. The large diameter rolls used in steel mills to roll steel into thinner plates or sheets is a hot rolled steel that has probably been forged into shape then machined into the final diameter. Some rolls are fabricated from hot rolled steel plates into shape. This allows the ability to add internal cooling paths to keep the roll from overheating.
Q:AR 15 223 AMMO brass vs steel?
The Wolf ammo and the rest of its ilk also has steel bullet jackets, so it will wear your barrel faster than copper jacketed ammo. Plus you can't reload it. I've also seen a few manufacturers say not to use it as pressures may be erratic. I wouldn't buy it to shoot unless I was shooting it in someone else's rifle, I would buy it to stash though.
Q:What is harder Gold or steel?
steel. gold is pretty soft.
Q:Can a 1000lb hollow steel ball float in water?
sure, if the volume of air is about 7 times the volume of steel, the specific weight of the steel/air system would be below 1.0 and it will float. How do you think ships float?
