Introduction
On 15 October 2025, local time, in the town of Martinton, Illinois, USA, a giant 27-metre-high grain silo suddenly made a loud noise and collapsed! About 816 tonnes of soybeans stored inside gushed out like a dike flood, and people around it panicked and fled in all directions. Fortunately, the accident caused no casualties. The cause of the accident is still under investigation, according to eyewitnesses, before the collapse of the granary wall has cracks.
This incident quickly hit the headlines and made people wonder: how can the safety of storage facilities be child’s play? As a foreign trade specialist in the steel industry, I can’t help but think that similar accidents could have been avoided if high quality ASTM A516 steel plates had been used to build such storage facilities.
Core Properties of ASTM A516
ASTM A516 steel plate is a carbon steel plate under the American Society for Testing and Materials (ASTM) standard, designed for pressure vessels in low to medium temperature environments. It is available in several grades, such as A516 Gr 70, A516 Gr 65 and A516 Gr 60, with A516 Gr 70 being the most popular “star product”. This steel plate is known for its excellent mechanical properties: tensile strength of up to 415-580 MPa and a minimum yield strength of more than 265 MPa.
What’s more, it has excellent notch toughness and weldability, and remains tough and non-brittle even at temperatures as low as -46°C. This is like a tough, tough, tough, tough steel. It is like a battle-hardened warrior who can still stand up under extreme conditions.
Applications of ASTM A516
Why is ASTM A516 steel plate suitable for storage facilities? In the case of grain silos, most traditional silos are built with concrete, but concrete is prone to deterioration and cracking, especially when storing large quantities of grain such as soya beans, where internal pressure and humidity changes accelerate corrosion. If A516 is used to make large steel silos for grain storage, these silos are able to withstand significant vertical pressure and lateral loads to ensure food security storage.
For example, in the petrochemical and agricultural sectors, A516 steel plates are commonly used to build tanks and silos that are resistant to corrosion, fatigue and impact. Lighter and easier to install than concrete, A516 plate can also be hot rolled or normalised to improve durability.
So if the collapsed silo had been reinforced with A516 Gr 70 steel plates, perhaps the cracks wouldn’t have appeared so easily and the soya beans wouldn’t have “blown up” and poured out.
More than that, the uses of A516 steel plate go far beyond imagination. In the oil and gas industry, it is the material of choice for pressure vessels and boilers; in the chemical industry, for heat exchangers and reactors; and in construction and transport, even to make railway carriages and bridge components. Its low carbon content (no more than 0.28 per cent) ensures good weldability, while added elements such as manganese, phosphorus and sulphur further enhance strength and toughness.
A516 complies with international standards such as the ASTM A516 standard, which is not only of excellent quality, but also helps companies save on maintenance costs.
