Whether hardess of nm500 steel plate can be quenched to obtain martensite

We are a professional hardess of NM500 steel plate steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product hardess of NM500 steel plate quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

ASTM A 53 hardess of NM500 steel plate covers seamless and welded steel pipe with nominal wall thickness. The surface condition is usually black and hot-dipped galvanized. ASTM A 53 hardess of NM500 steel plate is produced mainly for pressure and mechanical applications, and is also used for transport of steam, water, gas line pipes.

The advantages of hardess of NM500 steel plate, carbon steel: First of all, the price of carbon steel is low. Compared with stainless steel, galvanized steel, alloy steel, etc., the carbon steel has a great advantage in price. It is a good choice for manufacturers and merchants such as construction sites that use building materials in large quantities. Secondly, the carbon steel is easy to process. In the early days, steelmaking technology was underdeveloped. It was very difficult to manufacture high-precision steel, and carbon steel is widely used.

With the increase of temperature, the yield limit of hardess of NM500 steel plate will decrease monotonically, but the tensile strength of hardess of NM500 steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of hardess of NM500 steel plate. Near the blue brittleness temperature, the hardess of NM500 steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of hardess of NM500 steel plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

hardess of NM500 steel plate, SA36 steel plate is one of our main product, it is belong to the carbon and low alloy high strength steel plate. We can supply the different sizes of SA36 steel plate. And the rolling size of SA36 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the SA36 steel coil thickness should not exceed 25 mm.

S355J2 hot rolled steel plate executive standard: EN10025-2S355J2 hot rolled steel plate delivery status: control binding, normalizing rolling, normalizingThe European standard S355J2 hot rolled steel plate is available from hardess of NM500 steel plate stock and can be cut and processed according to the requirements of customers; the futures can be produced according to your requirements, and our S355J2 hot rolled steel plate price is preferential and the delivery time is fast, welcome to contact and purchase.

Our company will accept the product quality objection registration record, pass it to the hardess of NM500 steel plate production unit and relevant departments, and timely coordinate the supervision of product hardess of NM500 steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
