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:How do we use steel ?
Strength of metals is normally measured by the tensile strength as the main measure although this is not the only property as hardness is another big factor. Basically, iron is soft and steel is hard. Plain iron is stretchy and does not corrode quickly, whereas steel is much stiffer and corrodes more quickly. The tensile strength of cold worked iron is about half that of an average steel, likewise the hardness is about half that of steel too. Pure iron, which is rarely used, is even weaker and softer again and a bit more like softer materials like copper and aluminium. Where confusion comes in is that there is another iron - Cast Iron - which is totally different to both iron and steel. Cast iron is very hard and tough but incredibly brittle so its properties are very different.
Q:What minerals are mixed to make steel?
It depends on the type of steel that you want. For example- A cold drawn carbon steel spring wire consists of Carbon,Silicon,Manganese,sulphur potassium. If you want to make an alloy steel you can also add chrome,vanadium , nickel etc. It depends on the combinations and percentages of each used.
Q:Steel frames are completely out of the game...?
Plenty of racers are still winning races on steel bikes. Not at the pro level, but that has more to do with the fact that carbon bikes generate more profit for sponsors, than any other factor. Steel bikes are more durable than alu or carbon. The super-light bikes being sold today in carbon tend to break more often and only last a few years on average before needing replacement. A steel bike will last for decades and can shrug off things like minor crashes, scratches dings and dents that would render a carbon frame unsafe. Then there's the mechanical aspect. Carbon frames and parts require a torque wrench and special compounds to prevent accidental crushing from over-tightening. Many home mechanics end up ruining thier bikes because of simple user error. Alu frames are not so bad in this regard; these days I think alu bikes are the price/performance leaders in road bike frames.
Q:Golf: Graphite shaft, or Steel shaft sand wedge?
The way to resolve the selection is to go with the shaft that matches the other clubs in your set. If you have steel shafted irons go with steel. You will find the similar feel when you hit shots is most important.
Q:Nylon vs Steel Guitar?
Nylon is easy to use for beginners but steal sounds better.
Q:Several reading methods of steel tape measure
Direct reading method when measuring the steel tape zero scale alignment measurement starting point, proper tension (stretching force with steel tape tension or tension on the calibration ruler identification shall prevail, with the spring balance measure), direct reading measurement end point corresponding to the scale scale.
Q:Mag. Wheel (steel and aluminum info)?
Negative facts for steel wheels: (1) Not as many style choices as aluminum. (2) Rust easily even when painted or powder coated, due to rock chips. (3) Heaver than aluminum, as far as fuel economy. Negative facts for aluminum wheels: (1) More sensitive to proper torquing of lug nuts. IE torque must be checked more often. (2) Susceptible to impact damage from road hazards much more than steel. (3) Need constant attention to prevent oxidation. Are these what you are looking for? I hope so. Wingman
Q:Does shooting steel case ammo in a AR-15 ruin/damage the gun?
Two reasonable answers here. But let me say this...I just don't like the idea of steel touching steel at a high rate of speed (like when it's being cycled in and out of the chamber of a rifle). I can't help but feel that some sort of erosion is going to occur to the chamber of the rifle - which obviously isn't a good thing. If it were me, I would stick with firing brass casings only. The only gun I would fire steel casings through would be a cheaper SKS
Q:8cr13mov steel thoughts?
8Cr13MoV is a decent blade steel...not a great steel, but about as good as you will generally find without paying much higher prices. It's used by a number of well known knife makers... It's basically equivalent to AUS-8 and will work and hold an edge reasonably well for most basic cutting chores. *************************************** From Wikipedia, the free encyclopedia: 8Cr13MoV, a Chinese stainless steel tempered at the Rc56 to Rc58 range and used in the Tenacious, Persistence, Ambitious, Resilience, Grasshopper, Kiwi3 and Byrd lines of knives. Often compared to AUS-8, but with slightly more Carbon.
Q:Steel and Iron Ore?
Then people like Bull tell you the country is going down yet Lakshmi and Mark Mobius(read last week's FM) show confidence in SA. Sieman, IBM and CNBC are investing millions in the country. Now who do believe?
