Our Services

Foshan Dongyuan Trading Co., Ltd. is a company dealing with a variety of products, whose major products are stainless steel and related accessories such as stainless steel valves, sculptures of all kinds of shapes as well as spheres covering many sizes. Having been in this trade for 4 years, we have succeeded in satisfying our clients and customers throughout the world for our products are of excellence and superiority. Customers’ needs are always our priority. Please rest assured that once we start meeting your requirements on any possible products we could come up with, no worries will incur about the quality, prices and all sales services. We are accountable and obligated for our customers’ comfort in terms of product quality, service and after-sales.

 

 

Company Information

 

We are capable of providing stainless steel spheres/balls almost as per your specific requirements. Products include hollow stainless steel spheres (ranging from 6mm to 2500mm in diameter), available for delivery if we have it in stock or delivered within 15 days. Wall thickness of spheres varies from 0.4mm to 3mm. Shaped by water pressure, our products could be mirror polished without any seams noticeable on the surface; meanwhile, welding and then sandblasting spheres is a another way to produce mirror polished spheres also without detectable traces on the spheres. Having been offering services for our customers worldwide, a variety of products also fall under many categories of our products. Staidness steel spheres, hollow or solid, of all sizes are our major products, and brass and bronze balls come along. Hollow reflective stainless steel spheres of enormous sizes are amongst the top sales in our products. Perforated stainless steel spheres or sculptures of 304 or 316 are also our hot products. Not to mention we have done considerable amount of drilled stainless steel balls or spheres with holes of many sizes. Our products are of professional and advanced technology with cost-effective craftsmanship and favorable delivery time. 

 

Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.

Types 304 and 304L exhibit excellent resistance to corrosive environments such as the chemical, textile and petroleum industries.Type 304 and 304L are found suitable in the food and dairy industries as well as excelling in rural and industrial atmospheric exposure.By reducing the carbon content in Type 304L, welding operations will not cause carbide precipitation that can lead to inter-granular corrosion. The maximutemperature  to which Type 304 can be exposed continuously without appreciable scaling is about 1650 °F (899 °C).For intermittent cyclic exposure, the maximum exposure temperature

is about 1500 °F (816 °C).Type 304 is non-hard enable by heat treatment.Annealing: Heat to 1900 – 2050 °F (1038 – 1121 °C), then cool rapidly.Thin strip sections may be air cooled, but heavy sections should be water quenched to minimize exposure in the carbide precipitation region.Stress Relief Annealing: Cold worked parts should be stress relieved at750 °F (399 °C) for 1/2 to 2 hours.High hardness and strength  are achieved through cold working. In the annealed condition, Types 304 and 304L are very ductile and can be cold worked easily by roll forming, deep drawing, bending, and other common fabricating methods. Since the material work hardens rapidly, in-process annealing may be necessary to restore ductility and to lower hardness.
