Popular questions

Do you have a minimum order amount?

NO! – No minimum order size! junying realizes requirements often start off small, such as research and development projects. So we don’t have a minimum!

How fast can you ship or deliver my parts?

Most parts can be shipped or delivered within 4-5days.

What are CNC machining capabilities?

We mill and turn low quantities of parts very quickly. Typical quantities are one to 1000 pieces and manufacturing times are 3 business days. We offer product developers parts machined from engineering-grade materials that are suitable for functional testing or end-use applications.

What are stocked materials for machining?

We stock a variety of plastic and metal materials from ABS, nylon, PC, and PP to stainless steel, aluminum, copper, and brass. See a full list of more than 40 stocked materials for milling and turning. At this time, we do not accept customer-supplied material for machining.

What Does the L After a Stainless Steel Type Mean?

The L indicates low carbon grades. The “L” grade material helps reduce the possibility of carbide precipitation forming during processes such as welding. Carbide precipitation may then lead to intergranular corrosion attack where the material becomes more sensitive to possible corrosion. Typically the carbon is kept to .03% or under; however, depending upon the specification or standard referenced it may vary.

Is Stainless Steel Magnetic?

Because the predominant element in steel—iron—is magnetic, most steels do have magnetic properties. This is true of many stainless steels, too. All the ferritic, martensitic, and precipitation hardening grades are magnetic.
The high nickel and chromium contents of the T300 series of austenitic stainless steels renders the alloys initially non-magnetic. For instance, a common austenitic steel, 304 stainless contains 18% chromium and 8% nickel. However, these alloys can also become magnetic during the cold-working processes used to harden them.

How Do You Harden Stainless Steel?

Some types of stainless steel can be hardened through heat treatment while other types need to be cold worked. Examples of cold working include swaging or drawing.
