X120Mn12 망간강 팁

Introduction to X120Mn12 Manganese Steel
X120Mn12 manganese steel, 경질 망간강 또는 망간 경질강이라고도 함, 집중적인 가공경화를 통해 원래의 낮은 인장강도와 경도를 대폭 향상시켰습니다.. 이 과정은 담금질된 상태에서 발생합니다., 높은 초기 인성을 손상시키지 않으면서 내마모성을 향상시킵니다.. The steel’s work-hardened surface greatly increases its resistance to wear, making it ideal for applications involving shock and impact loads. The steel is also suitable for bending, flanging, and punching due to its toughness. 하지만, the use of carbide tools at room temperature for processing is limited.

Applications of X120Mn12 Manganese Steel Sheet
X120Mn12 manganese steel sheet is commonly used in various heavy-duty applications, 포함:

Sandblasting machine hangers
Crushing jaws and jaw inserts
Excavator bolts and bushings
Clamping teeth
Impact elements in impact and centrifugal mills
Safety technology products such as protective grilles, 문, 클래딩, 그리고 안전판

The material is predominantly employed in industries where large shock and impact forces are encountered.

Welding X120Mn12 Steel Sheet
X120Mn12 steel sheet can be welded using both electric and autogenous methods. 하지만, autogenous welding may lead to the loss of manganese and carbon, which is why electric welding is preferred. For electric welding, electrodes with 0.8% – 1.0% 탄소와 15% – 18% manganese content are recommended. It is important to note that the weld’s wear resistance is slightly lower than the material itself.

X120Mn12 (1.3401) 열처리
X120Mn12 is a heat-treatable, austenitic manganese steel with a high manganese content. This steel achieves its wear resistance through the impact and pressure experienced during use. The initial hardness of X120Mn12 is approximately 200 HB (브리넬 경도) and increases to around 500 HB as the material undergoes work hardening on the surface while maintaining a tough core. This unique property makes X120Mn12 easy to process using conventional methods such as plasma cutting or laser cutting.

Shearing is also possible with powerful machines, even for thicknesses up to 10 mm. Drilling can be performed using special cobalt-alloyed ultra-high-speed steel drill bits with a reinforced core. Despite its high carbon content, X120Mn12 offers good weldability and does not require preheating.
