What to know?

Austenitic:
Austenitic steels have austenite as their primary phase (face centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. Austenitic steels are not hardenable by heat treatment. The most familiar stainless steel is probably Type 304, sometimes called T304 or simply 304. Type 304 surgical stainless steel is an austenitic steel containing 18-20% chromium and 8-10% nickel.

Ferritic:
Ferritic steels have ferrite (body centered cubic crystal) as their main phase. These steels contain iron and chromium, based on the Type 430 composition of 17% chromium. Ferritic steel is less ductile than austenitic steel and is not hardenable by heat treatment.

Martensitic:
The characteristic orthorhombic martensite microstructure was first observed by German microscopist Adolf Martens around 1890. Martensitic steels are low carbon steels built around the Type 410 composition of iron, 12% chromium, and 0.12% carbon. They may be tempered and hardened. Martensite gives steel great hardness, but it also reduces its toughness and makes it brittle, so few steels are fully hardened.

There are also other grades of stainless steels, such as precipitation-hardened, duplex, and  cast stainless steels. Stainless steel can be produced in a variety of finishes and textures and can be tinted over a broad spectrum of colors.

 

 

 

 

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 craftmanship and favorable delivery time. 

 

 

FAQ

 

Do you customize? 

--Yes, the majority of our business is either using our in-house designs, or further developing your own designs presented to us. We can modify by re-scaling, re-sizing, adding signage / script etc. 

 

Can I choose a specific rust color or pattern? 

--Each product has its own unique character and finish. The color variations are part of the intentional design and, being an organic process, it cannot be controlled.

 

What is the weight? 

--It depends on the subject products. If it is a standard size sphere, then it would be easy for us to give you an estimate weight regardless of the error or deviation. If it is a customized product, all designs vary according to intricacy and negative/positive space, and if framing is necessary. 

 

What is your delivery process?

-- Local deliveries are notified before dispatch to confirm a suitable delivery time slot.  Rural, interstate & international deliveries are dispatched using express or sea transportation as per our client’s request . 

 

Is there any maintenance required?

-- 304 steel is enduring indoors and should be kept from water. 316 is the best steel on the market with overwhelming capability against water-erosion. Long term exposure to the elements and environment will cause changes and a continuation of the rusting process. If this is not desired, we recommend a small degree of maintenance.

Corrosion Resistance

Excellent in a range of atmospheric environments and many corrosive media - generally more resistant than 304. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C. Considered resistant to potable water with up to about 1000mg/L chlorides at ambient temperatures, reducing to about 500mg/L at 60°C.

316 is usually regarded as the standard “marine grade stainless steel”, but it is not resistant to warm sea water. In many marine environments 316 does exhibit surface corrosion, usually visible as brown staining. This is particularly associated with crevices and rough surface finish.

Heat Resistance

Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of 316 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 316L is more resistant to carbide precipitation and can be used in the above temperature range. Grade 316H has higher strength at elevated temperatures and is sometimes used for structural and pressure-containing applications at temperatures above about 500°C.

Heat Treatment

Solution Treatment (Annealing) - Heat to 1010-1120°C and cool rapidly. These grades cannot be hardened by thermal treatment.
