Q:What is the weight?
A: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.
Q: What is your delivery process?
A: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 .
Q: Is there any maintenance required?
A: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.
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.
SAE 304 stainless steel, also known as A2 stainless steel (not the same as A2 tool steel) or 18/8 stainless steel, European norm 1.4301, is the most common stainless steel. The steel contains both chromium (usually 18%) and nickel (usually 8%) metals as the main non-iron constituents. It is an austenite steel. It is not very electrically or thermally conductive, and is non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes. It also contains 17.5-20% Chromium, 8-11% Nickel, and less than 0.08% Carbon, 2% Manganese, 1% Silicon, 0.045% Phosphorus, and 0.03% Sulfur .
304 stainless steel is used for a variety of home and industry uses, such as screws, machinery parts, fabrics and other uses.
