| Sinotech ASTM A128 High Manganese Steel Investment Castings (2024)
ASTM A128 Grade A (UNS J91109) is Manganese steel for abrasive casting applications. ASTM A128 / A128M – 93(2017) Standard Specification for Steel Castings, Austenitic Manganese ASTM A128 Grade A Casting Chemical Composition: Carbon: 1.05-1.35 Manganese: 11.0 min Silicon: 1.00 max Phosphorus: 0.070 max
Investment casting ASTM A128 is similar to investment casting other steels, but the heat treatment is far more exacting and difficult. Sinotech begins with your 3-D CAD drawings and uses advanced modeling software to create precision mold designs. The modeling assures uniform heat flow and cooling through strategic placement of gates and gas vents.
First, parts are strung along a steel wire to maintain proper separation for adequate air flow, ensuring uniform heating and cooling. Strings of parts are coiled into a nest to further promote uniform air flow. The parts remain in strings through the heat treating and quenching processes.
Metallurgical Acceptance. Metallurgical acceptance is determined in accordance with the American Society for Testing of Metals Atlas of Microstructures of Industrial Alloys according to agreed upon acceptable microstructures. A section of the part is cut and treated with an etchant used to prepare the specimens.
Sinotech can ensure excellent ASTM A128 investment castings from our Pacific Rim factories and is very price competitive. Sinotech is dedicated to managing your casting project and delivering parts to you at lower prices but with the same quality, service and terms as a domestic supplier.

High Manganese Steel Plates are composed of steel containing 11% to 14% manganese. The material's high wear resistance and toughness make it an ideal choice for various applications in a range of industries. Many industries that require wear-resistant parts widely use it, including mining, construction, and metallurgy.
Because of its self hardening properties, manganese steel has been used in the mining industry for many years – cement mixers, rock crushers, crawler treads for tractors, elevator and shovel buckets – as well as in the rail industry (switches and crossings) and other high impact environments.
Both high manganese steel plate and high carbon steel are known for their exceptional strength. However, high carbon steel is known for its higher tensile strength, while high manganese steel plate is known for its excellent toughness.
Manganese increases hardenability and tensile strength of steel, but to a lesser extent than carbon. It is also able to decrease the critical cooling rate during hardening, thus increasing the steels hardenability much more efficient than any other alloying elements.
Two of the strongest grades of steel are EN24T and T45 which are widely used across engineering, aeronautics, and motor sport due to their reliable mechanical properties.
Most stainless steel ordered around the world is Grade 304. It offers the standard corrosion resistance, formability, strength, and easy maintenance for which stainless is known. While 316 comes in second in terms of quantities sold, it offers vastly superior corrosion resistance to chlorides and acids.
What is the difference between ASTM A53 Grade A and Grade B? ASTM Grade B has higher mechanical requirements, different chemical composition, and higher test pressures than Grade A. Grade B meets and exceeds all of the properties of Grade A.
It has nominal composition of iron, 1.0 to 1.4 % carbon and 10 to 14% manganese in a 1 to 10 ratio. The present paper deals with a comprehensive analysis on the overview of high manganese steel casting.
ASTM A106 Grade B is a mild steel pipe material usually used in industrial plants, power plants, power plants, refineries, and chemical plants. ASTM A106 GR. B Carbon Steel Seamless pipes must be solution annealed according to the heat treatment part to restore the ferrite.
Although it's known for increasing the strength and hardness of steel, too much manganese can make steel brittle and difficult to work with. There are also issues in terms of its availability.
Manganese can reach a hardness score of almost 600 BHN, giving it about 5 times the hardness of mild steel, and almost 3 times the hardness of annealed stainless steel.
This type of steel is often used in the construction of residential buildings, as it can withstand high levels of stress and strain. Plus, manganese steel is resistant to rust and corrosion, making it a great choice for homes in humid or salty climates.
ASTM Method E-45 is the standard test method for determining the inclusion content of steel. Methods A, B, C, D and E cover a number of recognized procedures for determining the nonmetallic inclusion content of wrought steel. Macroscopic methods include macrotech, fracture, step-down, and magnetic particle tests.
C954 Standard Specification for Steel Drill Screws for the Application of Gypsum Panel Products or Metal Plaster Bases to Steel Studs from 0.033 in. (0.84 mm) to 0.112 in. (2.84 mm) in Thickness.
ASTM A751. These test methods and practices cover definitions, reference methods, practices, and guides relating to the chemical analysis of steel, stainless steel, and related alloys. They include both wet chemical and instrumental techniques.
ASTM International. This specification deals with the standard types and grade requirements of seven-wire, uncoated steel strands for use in the construction of pre-tensioned and post-tensioned pre-stressed concrete. The two types of strand are low-relaxation and stress-relieved (normal relaxation).
