Our Services

  1. Sand Casting

    Casting Quality focus on Metal Parts industry, we provide professional service in Metal Casting field.

    Sand Casting is a popular metal form method, are suitable for all materiel, such as grey iron, ductile iron, malleable iron, carbon steel, stainless steel, aluminum and bronze.

  2. Investment Casting

    also named as precision lost wax casting, mainly suitalbe for carbon steel and stainless steel parts. We also provide grey iron and ductile iron and aluminum and bronze parts by investment casting. It can achieve the best appearance with good tolerance

  3. Shell Casting

    Shell casting method is a good option to replace investment casting and sand casting. the quality is better than sand casting parts, suitable for bulk production.

Stainless Steel GradeLCC Chemical Composition / Physical Properties %
(max, except where range is given)

For each reduction of 0.01 % below the specified maximum carbon content, an increase of 0.04 % manganese above the specified maximum will be permitted up to a maximum of 1.10 % for LCA, 1.28 % for LCB, and 1.40 % for LCC.

Ni/Cr/Mo/Cu/V—The total content of these elements is 1.00 % maximum

LCC grade steel also needs Carbon Equivalent: CE=0.55Max

GR. LCC Heat treatment process:

Ferritic castings shall be furnished in the normalized and tempered or liquid-quenched and tempered condition. Castings shall be tempered at a minimum of 1100°F [590°C], followed by cooling in air or liquid

Castings shall be allowed to cool below the transformation, range directly after pouring and solidification before they are reheated for normalizing or liquid quenching.
