“即使是最好的剑浸入盐水中最终也会生锈。” “ Jíshǐ shì zuì hǎo de jiàn jìnrù yánshuǐ zhōng zuìzhōng yě huì shēng xiù.” "Even the finest sword plunged into salt water will eventually rust.”

Natural explanation: Why are swords soaked in salt water more likely to rust?

 Oxygen is dissolved in salt water, and the iron swords will undergo oxygen absorption corrosion. After corrosion, a loose and porous structure will be formed on the surface of the iron swords, which is easier to absorb oxygen, and then corroded, and the iron swords are more likely to rust. Iron rust requires air and a certain humidity. The condition for iron to rust is that iron is in contact with oxygen and water at the same time. Table salt is an electrolyte. In humid air, a thin water film will form on the iron surface, and the water film will dissolve in carbon dioxide, sulfur dioxide, hydrogen sulfide and other gases in the atmosphere; once the water film contains certain hydrogen ions, the iron surface will A thin film of electrolyte solution forms and forms a primary battery with iron and a small amount of carbon. Since hydrogen gas is continuously released during the corrosion process, it is also called hydrogen evolution corrosion, which is corrosion caused in an acidic environment. If the acidity of the water film adsorbed on the steel surface is weak or neutral, but a certain amount of oxygen is dissolved, oxygen absorption corrosion will occur at this time. If there is salt in it, it will speed up the movement of electrons in the solution and enhance the conductivity of the electrolyte solution. The higher the salt content, the faster the rust rate. Salt water can accelerate the rust rate of iron.

"Let's talk about knives" Stainless steel = no rust? Stainless steel will not only rust but also corrode!

 Stainless Steel = No Rust? 

 Can this equation hold? 

 Will stainless steel really not rust? 

 But what is disappointing is that although there is the word "stainless" in stainless steel, it will also rust. Almost all types of stainless steel can rust under certain conditions. 

 And this content is to explain why stainless steel rusts, how to prevent stainless steel from rusting, and how to deal with stainless steel rusting. 

 We all know that different types of steel have different performance characteristics. To understand the reasons for their different performance characteristics, it is necessary to understand the construction of steel.

 Steel is not just made of iron, each steel has different constituent elements added to it. Such as carbon, chromium, nickel, molybdenum, silicon, tungsten, cobalt, manganese and other elements. Using these different elements, steel manufacturers can produce different alloy steels. Some steels have high toughness, others have high hardness; some steels have poor rust resistance, and some steels have strong corrosion resistance. It's all about carbon.

Spiritual application:  Matthew 5:13  Jesus said, "You are the salt of the earth. But if the salt loses its saltiness, how can it be made salty again?

James 3:11-12, Can both fresh water and salt water flow from the same spring?  My brothers and sisters, can a fig tree bear olives, or a grapevine bear figs? Neither can a salt spring produce fresh water.

Even the finest sword plunged into salt water will eventually rust. Regardless of the hardness of human hearts ( analogy as a sword )which constantly withstand and go against God's divine word of life, when it constantly come in contact with the washing  of the salty (Christians)  water of sharing God's word, it will gradually be broken down , i.e. hardness rust / corroded.  

Ephesians 5:26  That he might sanctify and cleanse it with the washing of water by the word,
