Carbon Steel LCA(J02504)

LCA is one cheap carbon steel grade which listed in /352M standard only. UNS code is J02504.  It’s not a popular grade for low temperature application. www.castingquality.com

Casting Methods in Casting Quality Industrial:

  • Sand Casting
  • Investment Casting (Lost Wax Casting, Precision Casting)

LCA (UNS J02504) Equivalent Steel Grade: www.castingquality.com

AISI 1020

Reference Casting Standards:

Standard Specification for Steel Castings, Ferritic and Martensitic, for Pressure-Containing Parts, Suitable for Low-Temperature Service.

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.

  4. CNC Machining

    CNC Milling, CNC turning with 5 xix CNC center, we provide precision machining for all castings based on customers design drawings.

  5. CAD Design

    Mechanical Design service based on customers requirement, our software is Solidworks and AutoCAD.

  6. Tools/Mold Design

    Mould design and production will be served for metal casting ad plastic injection industry. Based on our more than 10 years experience, we supply professional molds for our customers in Europe and North American.

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

LCA grade steel also need Carbon Equivalent: CE=0.50Max

CE=C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15

LCA Heat treatment process: www.castingquality.com

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
