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:Can I load my own steel core ammo?
You don't know the law regarding selling steel core ammo quite as good as you think you do.
Q:Are steel casings reloadable?
you're not supposed to but if there's a will, there's a way. suppose it's the end of the world and you're just about to run out of ammunition, you can reload steel cases by drilling the primer pocket out to fit either a small boxer primer or large boxer primer. and drilling out a flash hole too. the cases must be from your gun and be able to chamber/extract without resizing. steel cases become brittle after a few uses, which become dangerous to reuse more than once. however if it's one of those situations you need ammo, it can be reloaded at low pressure a few dozen times, just give it a thorough inspection between reloading.
Q:Can a bear bend steel?
depends on the steel thickness and positioning. frm your question I'm guessing you're not really well versed in steel framing or use... im guessing whatever you build, a bear can destroy. if i was to build it not even 100 bears can destroy it. it doesn't require much steel, it's just about bracing the positing of steel and some design.
Q:Shaft stiffness in steel irons???
If i understand you correctly, i think you misunderstand shafts. Steel shafts vs. graphite shafts these days is more of a competition of weights, not flexibility. Both steel and Graphite have different flex profiles available from Ladies (L) to super stiff (X). Graphite may feel a little more whippy than steel because of the lighter weight. Shafts will vary by company as well. Stiff from True temper may not be as stiff as one from Aldila, or vice verse. You can also make a shaft play stiffer or more flexible by where you cut the length. This is called tipping. Take more from the bottom and it will be stiffer, more from the grip end and it will play more flexible.
Q:What is the Shear Modulus of Steel and Silver?
Modulus Of Rigidity Of Steel
Q:Greatest steel guitar songs in country music history?
Q:Carbon Steel or Stainless Steel? ?
If your talking about a folding pocket knife, I think that it's basically six one way and a half dozen the other. I actually do prefer stainless for my pocket knives. I don't want to oil a knife to the degree I feel carbon requires, only to then stick it my pocket to attract dirt to the knife and oil to my pants. I'm the exact opposite on sheath knives though. I like 1095 carbon steel, plain edge sheath knives. I'll thrash on them HARD, and I rarely have major edge problems. Of course, I require them to be coated with some kind of powder coat or the like, because they can rust, but I do try and keep them clean and dry when in the sheath, so they won't pit the uncoated edge. My reasons for this sheath knife preference is multi-fold. First, these knives are simply affordable. I don't spend $80 dollars on a outdoors sheath knife. I use the tool too hard to want to spend more. I don't like the more traditional stainless steels such as AUS-8, 420HC, and 440C (not to mention the HORRENDOUS 440A) because I feel that the all else being equal, a stainless blade will bend before a carbon blade will break. I also think that carbon holds an edge at least as well, if not better, than traditional stainless, and it's much easier to hone. I don't know much about these new laminates, other than the very hard, but not so tough. They seem to be POSSIBLY too brittle for my use. That, combined with the fact that they cost a FORTUNE, means that I just won't be considering them.
Q:whats the difference between weld steel and sheet metal?
galvanized steel gives off poisonous fumes when you weld it
Q:Best steel for a all purpose knife?
Besides the composition of the steel, the tempering is VERY important. I would buy a knife from a company with a good reputation and not worry about what material their metallurgist chose to make a high quality knife. You definitely do not have the knowledge of someone with a degree in metals and many years of experience.
Q:Science Question About Steel?
Carbon 'tempers' steel, by making it harder and less prone to bending (ductility). It fits the carbon atoms into the spaces in between the crystal lattice structure of the iron atoms. Too much carbon means the steel becomes more brittle, harder to weld and thus more likely to shatter under stresses which are perpendicular (shear forces) to the crystal structure of the molecules. It also is very difficult to work, requiring very high temperatures.
